What are co-badged cards?
A co-badged card refers to a debit or credit card that supports multiple card schemes. This is usually:
- an international network, such as Visa and Mastercard
- paired with a local brand, like Cartes Bancaires (France) or Dankort (Denmark).
Some regions have specific requirements that must be implemented in order to be compliant with local regulations.
It is your responsibility to meet these compliancy criteria.
Regulations
European Economic Area (EEA)
In the European Union, the Regulation (EU) 2015/751 sets the rules on how merchants should handle co-badged cards.
If you accept one of the following card networks, you are impacted by the regulation and must follow the guidelines outlined below:
- Bancontact (Belgium)
- Cartes Bancaires (France)
- Dankort (Denmark)
Other local card networks are available as co-badged cards in Europe - however only the three above can be used today for online card payments, and therefore are relevant for these guidelines.
Guidelines
Identify the supported card schemes
You do not have to accept all card networks.
However, when the customer is about to enter their card details, you must make it transparent and clear which card networks are accepted.
This can be done by presenting the logo and/or name of all the supported card networks.
If you decide to present the logo, they must have the same clarity, size and quality.
Choice of payment brand
If you accept all the card networks available on the customer’s co-badged card, you must enable the customer to choose which network they want to pay with.
You are free to set a default card network or pre-select one in order to reduce friction and optimize for cost. However, you must always honor the choice of the customer if they decide to override your preference.
In the case of recurring payments, the card network selected by the customer when they first entered their card must be honored for all subsequent payments.
To provide your users with the most seamless UX, we recommend you to use Primer Universal Checkout to automatically detect the networks as the user enters their card number.
Compliancy
This regulation was put in place in 2016.
Visa started conducting audits with the acquirers on the 31st of December 2023.
Failing to comply with the regulation exposes you to penalties defined by the acquirer and the card brand.
It is worth noting that "Bancontact Cards" is for now considered by Primer to be an independent payment method, and not a card network.
Other countries
Some countries outside of the EEA have other regulations related to co-badged cards. This is the case for Australia (with eftpos cards) and Saudi Arabia (with mada cards).
Primer does not support these card networks at the moment. This documentation will be updated when these card networks are added to Primer.
Get started with Drop-in Checkout
This feature is currently not available on Drop-in Checkout
Get started with Headless Checkout
In order to be compliant with the regulations, Headless Checkout enables you to
- detect the networks of the card number entered by the user
- retrieve the logo of each card network
- pass the card network selected by the customer to Primer
This feature is currently not available on React Native

Pre-requisites
This guide assumes that you have already integrated a card form with Headless Checkout.
Make sure to follow the "Get Started with Headless Checkout" first.
Step 1. Set the list of supported card networks in the client session
When creating a client session, it is recommended to pass the list of the card networks supported for this particular session. This ensures that the customer is not asked to choose a card network that you do not accept.
The card network should be sorted in order of preference. This enables us to identify the default card network to consider if the user enters a co-badged card.
123456
// POST /client-session{ "paymentMethod": { "orderedAllowedCardNetworks": ["VISA", "CARTES_BANCAIRES", "MASTERCARD"] }}
With the example above:
- If the user enters a “Visa & Cartes Bancaires” card, the default network will be Visa
- If the user enters a “Mastercard & Cartes Bancaires” card, the default network will be Cartes Bancaires
Learn more about orderedAllowedCardNetworks
in the API Reference.
Step 2. Detect the card networks
When you pass a full or partial card number by setting rawData
on the RawDataManager
object, Headless Checkout retrieves the list of card networks available for the card.
Retrieving the cards requires a network call, so primerRawDataManager(_:willFetchMetadataForState:)
is called to indicate that the network request has started.
After a response is received, the list of card networks is passed to your integration through a callback called
primerRawDataManager(_:didReceiveMetadata:forState:)
.
123456789101112131415161718
@objc optional func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, willFetchMetadataForState state: PrimerValidationState) { // ... Do nothing, or show a loading spinner ... } @objc optional func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, didReceiveMetadata metadata: PrimerPaymentMethodMetadata, forState state: PrimerValidationState) { if let cardMetadata = metadata as? PrimerCardNumberEntryMetadata { // ... Display received card networks to the user ... if let cardState = state as? PrimerCardNumberEntryState { // ... If you want to check which card number caused the returned card networks ... } } }
This callback returns the following data:
source
Enum value indicating how the card networks were retrieved.local
if the card networks come from the SDK, usually by leveraging the first few digits..remote
if the card networks come from Primer's server..localFallback
if Primer's server fails to be reached. This works similarly to.local
.
detectedCardNetworks.items
The list of all the detected card networks, including the ones that are not allowed.detectedCardNetworks.preferred
The first allowed card network in the detected card networks. Can benil
if the user entered a card that is not allowed.selectableCardNetworks?.items
The list of all the detected card networks that can be selected by the user.selectableCardNetworks
isnil
if Headless Checkout does not detect a co-badged card.selectableCardNetworks?.preferred
The card network selected by default, according to the order set inorderedAllowedCardNetworks
.selectableCardNetworks
isnil
if Headless Checkout does not detect a co-badged card.
The card networks returned by primerRawDataManager(_:didReceiveMetadata:forState:)
are PrimerCardNetwork
objects that contain the network id, its display name, and a flag, allowed
, that indicates whether the card network is in orderedAllowedCardNetworks
.
Learn more about primerRawDataManager(_:didReceiveMetadata:forState:)
in the API reference.
Less than 8 digits
If the user enters less than 8 digits, Headless Checkout cannot detect co-badged cards. Instead, Headless Checkout tries to detect major card networks using data available locally.
In this case:
source
is set to.local
detectedCardNetworks.preferred
contains the card network you should present to the userdetectedCardNetworks.items
contains all the detected card networksselectableCardNetworks
is alwaysnil
8 digits or more
If the user enters 8 digits or more, Headless Checkout attempts to make a request to Primer to retrieve the list of card networks available on the card using our BIN data.
In this case:
source
is set to.remote
selectableCardNetworks
is only available if the user has entered a co-badged card and both its detected networks are allowed for this sessionselectableCardNetworks.items
contains the list of card networks from which the user can select
If Headless Checkout fails to contact Primer, Headless Checkout falls back to a local detection (similar to when less than 8 digits are entered). In this case, source
is set to .localFallback
.
Let’s say orderedAllowedCardNetworks
is ["CARTES_BANCAIRES", "VISA", "MASTERCARD"]
If the user enters a card that is co-badged Visa and Cartes Bancaires:
detectedCardNetworks.items
isCARTES_BANCAIRES
andVISA
detectedCardNetworks.preferred
isCARTES_BANCAIRES
selectableCardNetworks?.items

PrimerCardNumberEntryState else { logger.error("Received non-card metadata. Ignoring ...") return } /* ... display spinner ... */ } func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, didReceiveMetadata metadata: PrimerPaymentMethodMetadata, forState cardState: PrimerValidationState) { guard let metadata = metadata as?

Step 3. Present the list of card networks and handle the selection
It is now your responsibility to present the list of card networks to the customer and enable them to choose the network they want to pay with.
To support you, Headless Checkout exposes the logos and human readable names of each card network via the AssetsManager
.
12345678
let cardAssets: [PrimerCardNetworkAsset] = networksForDisplay.compactMap { network in return PrimerHeadlessUniversalCheckout.AssetsManager.getCardNetworkAsset(for: network)} cardAssets.forEach { asset in // ... display the card, e.g. ... */ showCard(title: asset.displayName, image: asset.cardImage)}
When the user selects a card network, set rawData
, passing the relevant card network to let us know which the customer chose.
123456789
let selectedCardNetwork: CardNetwork = primerCardNetwork.value // Enum value for the network rawDataManager?.rawData = PrimerCardData( cardNumber: cardNumber, expiryDate: expiryDate, cvv: cvvNumber, cardholderName: cardholderName, cardNetwork: selectedCardNetwork // pass the enum value here)
Learn more about getCardNetworkAsset(for:)
in the API Reference.
Step 4. Create a payment with the selected card network
When the user clicks on “Pay”, call the submit
function to start the payment.
1
rawDataManager.submit()
If the card network was not provided via rawData
, Primer follows the order of preference given by the option orderedAllowedCardNetworks
passed in the client session API.
Testing co-badged cards
Primer Sandbox Processor supports a few co-badged test cards to enable you to test your integration.
You can find them in the list of test card payments.
Integrations
This is the current list of integrations that provide support for co-badged cards:
- Worldline SIPs
- Stripe
Notes
Slow and unreliable internet connection
When the customer's network connection is slow or unreliable, it is possible that the customer finishes entering their card details before Universal Checkout retrieves the card networks.
In order to keep the friction low, it is important to note that Universal Checkout does not block the creation of a payment while the card networks are being retrieved or if the card networks could not be retrieved at all.
This means that, if a co-badged card is entered, the customer is not guaranteed to be presented a card choice before they submit their card details.
Selected card network on the payment method data
In the case of a card payment, you can get the selected network by looking at paymentMethodData.network
.
We recommend against using paymentMethodData.binData.network
as it only contains the international card network.
