Modern card machines can do considerably more than accept a contactless payment.
For some businesses, the payment terminal can now become part of the customer loyalty programme — recognising returning customers, recording visits, awarding stamps or points, issuing rewards and helping merchants understand repeat purchasing behaviour.
This is often described as payment-linked loyalty, payment-embedded loyalty, card-linked loyalty or simply card machine loyalty.
But these terms do not always describe exactly the same technical setup.
A loyalty programme might sit:
- directly within a smart payment terminal;
- inside the EPOS system;
- within a payment provider's wider platform;
- through third-party loyalty software connected to the terminal;
- inside an existing CRM or customer platform; or
- across several of these systems at once.
This matters because choosing a loyalty programme can also affect your choice of card machine, merchant account, EPOS software and future payment provider.
The best loyalty solution is therefore not necessarily the one with the most attractive rewards screen. It is the one that fits the wider way your business takes payments and manages customers.
What Is Card Machine Loyalty?
Card machine loyalty allows part or all of a customer loyalty programme to operate through the payment terminal used at checkout.
Instead of presenting a separate physical loyalty card, entering a membership number or opening another app, customers may be able to participate while making their normal payment.
Depending on the provider and loyalty model, this might allow a business to:
- recognise returning customers;
- award digital stamps;
- issue loyalty points;
- provide money-off rewards;
- reward repeat visits;
- reward spending thresholds;
- issue future-use vouchers;
- run time-specific offers;
- run instant-win campaigns;
- track campaign performance; and
- connect payment activity with wider customer data.
For businesses with regular face-to-face customers, that can remove some of the friction associated with traditional loyalty schemes.
A café customer, for example, may not want another plastic card or separate app just to collect a coffee stamp.
If the customer's normal payment method can also participate in the loyalty journey, checkout can remain considerably simpler.
How Does Payment-Linked Loyalty Work?
The exact process varies between providers, but a typical payment-linked loyalty journey might look like this:
Customer pays → loyalty system recognises the participating customer → qualifying purchase is recorded → reward progress is updated → relevant reward is displayed or issued
Some payment-embedded loyalty platforms use the customer's chosen payment method as part of the loyalty-identification process.
Depending on the solution, customers may therefore participate using:
- a physical payment card;
- their mobile phone;
- a digital wallet; or
- a compatible wearable payment method.
The important word is depending.
Merchants should not assume every loyalty platform recognises every payment method in exactly the same way. Compatibility depends on the loyalty technology, payment terminal, payment application and provider integration.
Card Machine Loyalty vs Traditional Loyalty Cards
Traditional loyalty programmes usually require the customer to identify themselves separately from the payment.
That might mean:
- carrying a stamp card;
- scanning a barcode;
- presenting a loyalty card;
- opening an app;
- giving an email address;
- providing a telephone number; or
- asking an employee to add points manually.
Payment-linked loyalty attempts to combine at least some of those steps with the existing checkout journey.
That does not automatically make one model better than another.
A sophisticated retailer may actively want customers to use an app because it provides:
- mobile ordering;
- personalised offers;
- digital receipts;
- account management;
- gift cards;
- subscriptions;
- click and collect; and
- other customer functionality.
A coffee shop may want something much simpler.
The loyalty architecture should match the customer journey rather than forcing every merchant into the same model.
Four Ways to Add Loyalty to Card Payments
It is useful to separate the main approaches because businesses frequently compare products that solve different problems.
| Loyalty model | Where loyalty sits | Best suited to |
| Payment-embedded loyalty |
Payment terminal / payment application |
Fast face-to-face checkout and repeat visits |
| EPOS loyalty |
Till or EPOS platform |
Retail/hospitality requiring customer, stock and sales integration |
| App or CRM loyalty |
Customer app or CRM |
More sophisticated customer engagement and marketing |
| Connected loyalty |
Existing loyalty platform connected into payments |
Established businesses retaining an existing loyalty ecosystem |
Larger merchants may combine several of these.
For example, a retailer could use EPOS to manage the sale, a smart terminal to identify participating customers and a CRM to manage customer communications.
That is why loyalty should be considered as part of the wider integrated payments architecture.
What Rewards Can You Offer Through a Card Machine?
Modern terminal-based loyalty goes considerably further than the traditional paper stamp card.
Digital stamp cards
A digital version of:
Buy five coffees and receive the sixth free.
This model is often well suited to businesses with frequent repeat visits such as:
- coffee shops;
- bakeries;
- food-to-go businesses;
- salons;
- barbers;
- car washes;
- beauty businesses; and
- other regular-use services.
Points-based loyalty
Customers collect points based on visits, transaction value or another qualifying activity.
Points can then potentially be exchanged for discounts, products or other rewards depending on the programme design.
Spend-based rewards
The reward can be based on how much the customer spends rather than simply how many times they visit.
For example:
Spend £100 across qualifying visits and receive £10 towards a future purchase.
Instant-win rewards
Some payment-linked loyalty systems can introduce gamification at checkout.
A qualifying transaction might give a customer the opportunity to receive a future discount or reward.
Conditional offers
Merchants may also be able to create offers subject to conditions such as:
- minimum spend;
- day of the week;
- time of day;
- location;
- campaign dates; or
- future redemption periods.
This means loyalty can potentially be used not only to reward existing behaviour but to influence when and how customers return.

Can a Card Machine Recognise Returning Customers?
Some payment-linked loyalty systems can recognise a participating customer when they use a payment method that has been enrolled or associated with the loyalty programme.
This allows the system to recognise repeat activity without requiring the customer to present a separate physical loyalty card on every visit.
But merchants should understand exactly what customer recognition means within the product they are considering.
Ask:
- What identifier is actually used?
- Does the customer need to opt in?
- Does it work with physical cards?
- Does it work with Apple Pay or Google Pay?
- Does it work with watches and other wallets?
- Can the same customer be recognised across different locations?
- What happens if they use a different payment method?
- What personal information is retained?
- Can customer records be exported?
- Can loyalty information connect with an existing CRM?
These questions become particularly important for businesses that want more than a basic digital stamp card.
Payment Loyalty, Zeal and Lopay: What Is the Difference?
These names increasingly appear when businesses search for loyalty built into payment terminals, but they should not automatically be treated as interchangeable products.
Payment Loyalty
Payment Loyalty specialises in loyalty embedded into the payment process.
Its current merchant proposition includes payment-linked loyalty, gamified rewards, campaign management and integrations with supported smart payment terminals.
The customer's payment method can form part of the loyalty experience rather than requiring a separate traditional loyalty card.
Payment Loyalty supports integrations across different terminal environments, so the important question for a merchant is whether the particular combination of terminal, payment software and payment provider supports the functionality required.
Zeal
Zeal takes a broader payment-terminal software approach combining loyalty, customer recognition and customer insight on supported terminal estates.
Its current proposition can include points or stamps, optional customer-data capture and integration with an existing loyalty engine.
Zeal also works through payment-provider integrations, so availability depends on factors including the terminal model, payment application and provider relationship.
Lopay
Lopay approaches loyalty as part of its wider merchant payment proposition.
Its Business Terminal can provide payment-linked loyalty alongside card acceptance and point-of-sale functionality.
Lopay and Payment Loyalty announced a partnership to bring Payment Loyalty technology into Lopay's Android Business Terminal environment.
This is a useful example of why the market can initially look confusing:
The company supplying your card machine, the company processing your payment and the technology powering the loyalty experience do not always have to be the same company.
This is also where Merchant Advice Service takes a different approach.
Rather than starting with one loyalty product, we look at the complete merchant requirement:
Loyalty → Card machine → Payment provider → Acquirer → EPOS → Customer data → Integrations → Commercial terms.
MAS View: Do Not Choose a Payment Provider Just for Loyalty
A strong loyalty proposition is useful.
But it should not hide weaknesses elsewhere in the payment setup.
A merchant could choose a terminal because the loyalty software looks excellent and later discover that:
- transaction costs are uncompetitive;
- settlement is slower than required;
- the provider does not integrate with its EPOS;
- multi-site reporting is weak;
- the contract is restrictive;
- the acquirer is unsuitable for the business sector;
- online payments sit on a completely separate system; or
- switching payment provider later would mean losing the loyalty functionality.
The reverse is equally true.
The cheapest payment provider may not be the best option if it prevents the business from delivering an important customer experience.
Loyalty should form part of the provider comparison — not replace it.
Can You Add Loyalty to an Existing Card Machine?
Sometimes.
But not every loyalty application can simply be downloaded onto every payment terminal.
Compatibility can depend on:
- terminal manufacturer;
- terminal model;
- operating system;
- payment application;
- terminal-management platform;
- payment provider;
- acquirer;
- software certification;
- loyalty provider; and
- how the terminal has been configured.
Modern Android smart terminals can support significantly more software functionality than traditional card machines, but that does not mean every application is available on every Android terminal.
This is the same compatibility issue businesses encounter with integrated card machines and EPOS.
Before replacing an existing terminal estate purely to obtain loyalty, check whether the functionality can already be added to your current environment.
Which Card Machines Support Loyalty?
There is no reliable answer based purely on the brand printed on the hardware.
Loyalty applications have been deployed across smart terminals from manufacturers including PAX, Castles and Verifone, but merchants need to check the precise provider and software configuration.
For example:
A PAX terminal being technically capable of running loyalty software does not mean every payment provider supplying that PAX terminal offers the same loyalty application.
The same principle applies to other terminal manufacturers.
Ask about the actual configuration rather than simply:
“Do you supply Android card machines?”
Card Machine Loyalty vs EPOS Loyalty
This is one of the most important decisions for retailers and hospitality businesses.
Many EPOS systems already offer loyalty functionality.
That can include:
- customer accounts;
- points;
- discounts;
- gift cards;
- customer apps;
- purchase history;
- email marketing;
- digital receipts;
- promotional codes; and
- multi-channel customer profiles.
EPOS-based loyalty can be particularly useful when the reward needs to understand what the customer purchased, rather than simply the value of the transaction.
Consider this example:
“Buy five coffees and receive one free.”
A payment terminal can potentially recognise visits or spend.
But if the campaign needs to distinguish between:
- coffee;
- cake;
- lunch;
- alcohol;
- retail merchandise; and
- other product categories
the loyalty platform may also need access to item-level EPOS information.
This is why established retailers should consider retail EPOS and payments together.
Payment-Linked Loyalty vs EPOS Loyalty: Which Is Better?
Neither is automatically better.
Use the business requirement to determine where the loyalty intelligence should sit.
Payment-linked loyalty may suit you if:
- checkout needs to remain extremely quick;
- you want to minimise separate customer actions;
- repeat visit or spend behaviour matters most;
- you operate a relatively simple point of sale;
- you want loyalty directly within the payment journey; or
- you do not need detailed product-level loyalty rules.
EPOS-led loyalty may suit you if:
- rewards depend on particular products;
- you already have customer accounts in EPOS;
- loyalty needs to work with stock and product data;
- you operate gift cards or vouchers;
- loyalty needs to work across ecommerce and physical stores; or
- customer engagement forms part of a wider retail platform.
A connected approach may suit you if:
- you already have an established loyalty programme;
- you operate multiple locations;
- customer information sits in a CRM;
- you need online and in-store recognition;
- you have several payment providers or acquirers; or
- you need a longer-term customer-data strategy.
Can Loyalty Work Across Several Shops or Locations?
Yes, depending on the loyalty system.
But a multi-site merchant should establish whether the programme genuinely operates across the group rather than independently on each terminal.
Questions include:
- Can customers earn in one location and redeem in another?
- Can different shops run different campaigns?
- Can the head office manage campaigns centrally?
- Can performance be analysed by location?
- Can terminals sit under several merchant IDs?
- Can different legal entities participate?
- Can ecommerce purchases contribute?
- Does the programme still work if several acquirers are used?
The larger the estate, the more important these questions become.
Does Card Machine Loyalty Work With Apple Pay and Google Pay?
Some payment-linked loyalty providers support customer participation through mobile wallets and wearable payment methods as well as physical cards.
However, merchants should confirm this with the specific loyalty provider.
Do not assume that because a terminal accepts Google Pay or another mobile wallet for payment, the loyalty application will automatically recognise that wallet in exactly the same way it recognises a physical card.
Payment acceptance and loyalty recognition are related but separate technical functions.
What Customer Data Does Payment-Linked Loyalty Collect?
This depends heavily on the platform and how the merchant configures it.
Some loyalty propositions deliberately minimise traditional registration and personal-data collection.
Others can collect or connect information such as:
- customer contact details;
- visit frequency;
- purchase value;
- reward history;
- location;
- campaign participation;
- customer preferences; or
- other behavioural information.
A merchant should understand the distinction between:
recognising that the same participating customer has returned
and:
building an identifiable customer profile for marketing purposes.
Those are not necessarily the same activity.
If personal information is being collected, analysed or used for direct marketing, businesses also need to consider their data-protection and marketing obligations.
The loyalty provider should clearly explain what data is processed, for what purpose and which party is responsible for it.
Can Loyalty Data Be Used for Marketing?
Potentially, but collecting loyalty information does not give businesses unrestricted permission to market to customers.
If customer information is being used to profile behaviour or send personalised marketing, businesses need to understand the applicable UK data-protection and direct-marketing requirements.
For example, a loyalty platform may identify that a customer:
- visits every Friday;
- has not returned for six weeks;
- normally spends more than £50;
- responds to certain campaigns; or
- regularly shops at one particular location.
That information can be commercially useful.
But the business should be transparent about how customer information is used and ensure its marketing activity complies with the relevant rules.
Already have EPOS or card machines?

What Happens to Loyalty if You Change Payment Provider?
This is an important question that merchants should ask before committing to a loyalty solution.
Some loyalty systems are closely tied to a particular:
- payment provider;
- terminal application;
- terminal model;
- acquiring relationship; or
- EPOS platform.
If you later want to change payment provider, establish:
- whether the loyalty software can move;
- whether customer reward balances can migrate;
- whether existing customer recognition continues;
- whether campaigns can be exported;
- whether the replacement terminals support the software;
- whether customer data remains accessible; and
- whether the loyalty contract is separate from the merchant-services contract.
This should form part of any card machine provider migration.
A loyalty programme that successfully increases customer retention can ironically make the merchant much more reluctant to change payment provider if the loyalty data cannot move with them.
Provider flexibility should therefore be considered from the beginning.
What Should Multi-Site Retailers Ask?
For a larger retailer, loyalty can quickly become an infrastructure question rather than a simple terminal feature.
Before choosing a solution, establish:
- how many terminals are required;
- how many stores are involved;
- whether there are several merchant IDs;
- whether ecommerce must participate;
- whether customer accounts already exist;
- whether EPOS holds product-level purchase data;
- whether campaigns need central management;
- whether local stores need their own campaigns;
- whether the business already uses a CRM;
- whether several payment providers are currently used;
- how customer data will be governed; and
- what happens when terminals or payment providers change.
The solution that works perfectly for one café is not necessarily the right loyalty architecture for a 100-site retailer.
Customer Loyalty for Hospitality
Hospitality businesses can have particularly strong repeat-visit use cases.
These include:
- coffee shops;
- restaurants;
- pubs;
- bars;
- food-to-go businesses;
- hotels;
- leisure venues; and
- multi-site hospitality groups.
But hospitality loyalty may also need to work with:
- table ordering;
- booking systems;
- customer apps;
- delivery;
- gift cards;
- tipping;
- pay-at-table;
- online orders; and
- EPOS.
Again, the terminal cannot be considered in isolation.
Customer Loyalty for Retail
Retail loyalty often requires a broader view of the customer.
A retailer may want rewards to work across:
- physical stores;
- ecommerce;
- click and collect;
- customer accounts;
- gift cards;
- apps;
- returns;
- promotional codes; and
- multiple locations.
The loyalty programme may therefore need deeper integration with the retail EPOS system, ecommerce platform and CRM rather than operating exclusively at the terminal.
How Much Does Card Machine Loyalty Cost?
There is no single price for card machine loyalty.
Depending on the provider and setup, costs may involve:
- monthly loyalty software fees;
- per-terminal charges;
- payment terminal rental or purchase;
- merchant account fees;
- payment processing charges;
- EPOS subscriptions;
- integration costs;
- CRM costs;
- implementation fees; or
- enterprise licensing.
There is also the economic cost of the rewards themselves.
For example, a campaign giving customers £10 after spending £100 has a very different commercial effect from a free coffee after six visits.
A merchant should therefore evaluate:
Software cost + payment cost + reward cost + operational cost against increased visits, retention and spend.
The cheapest loyalty licence is not necessarily the programme delivering the greatest commercial value.
What Should You Compare Between Card Machine Loyalty Providers?
Before choosing a loyalty-enabled payment setup, compare the following.
Customer journey
How does the customer join, earn and redeem?
Payment-method recognition
Which cards, mobile wallets and wearable payments can participate?
Reward types
Does the system support stamps, points, spend rewards, instant wins, vouchers or more sophisticated campaigns?
Terminal compatibility
Which exact payment terminals and applications are supported?
Payment-provider compatibility
Does the loyalty system restrict which PSP, ISO or acquirer you can use?
EPOS
Can the loyalty platform connect to the till or use item-level transaction information?
Ecommerce
Can online purchases participate in the same loyalty programme?
Multi-site functionality
Can customers earn and redeem across locations?
Customer data
What information is collected and who controls it?
CRM integration
Can the data connect with an existing customer platform?
Reporting
Can the merchant measure visits, redemption and campaign performance?
Provider switching
What happens to customer data and rewards if the business changes payment provider?
Total cost
What does the entire payment and loyalty setup cost, not just the loyalty application?
The MAS Loyalty & Payments Test
Customer Journey → Loyalty Model → EPOS → Terminal → Acquirer → Data → Integration → Future Flexibility
We think businesses should work through loyalty in that order.
1. Customer journey
What behaviour are you actually trying to encourage?
2. Loyalty model
Do you need stamps, points, spend rewards, offers or a larger customer programme?
3. EPOS
Does the loyalty programme need product-level information?
4. Terminal
Which payment hardware supports the required functionality?
5. Acquirer and payment provider
Can the provider support both the business and the required terminal environment?
6. Customer data
What information is required and where will it sit?
7. Integration
What needs to connect with ecommerce, CRM, booking, EPOS or other software?
8. Future flexibility
Can you change part of the setup later without rebuilding everything?
How Merchant Advice Service Helps With Card Machine Loyalty
Merchant Advice Service looks across the wider payments market rather than representing one particular loyalty platform, card-machine manufacturer or acquiring bank.
That means we can consider loyalty alongside:
- card machines;
- merchant accounts;
- acquiring;
- EPOS;
- payment gateways;
- ecommerce;
- CRM;
- customer apps;
- multi-site payments;
- integrated payments;
- settlement;
- processing costs;
- existing contracts;
- provider compatibility; and
- future switching requirements.
For some businesses, a straightforward loyalty-enabled smart terminal may be sufficient.
For others, loyalty needs to form part of a wider retail or hospitality technology architecture.
Our role is to help you understand that requirement before exploring providers.
You can also browse Card Machine & EPOS Providers through The Payments Directory®.
