Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The supportedNetworks property of the BasicCardRequest dictionary contains an array of DOMStrings representing the card networks that the retailer supports (e.g. amex, mastercard).


supportedNetworks : [value [, ... value]]


An array containing one or more DOMStrings, which describe the card networks the retailer supports. Legal values are defined in the W3C's document Card Network Identifiers Approved for use with Payment Request API, and are currently:

  • amex
  • cartebancaire
  • diners
  • discover
  • jcb
  • mastercard
  • mir
  • unionpay
  • visa


The following example shows a sample definition of the first parameter of the PaymentRequest() constructor, the data property of which contains supportedNetworks and supportedTypes properties.

var supportedInstruments = [{
  supportedMethods: 'basic-card',
  data: {
    supportedNetworks: ['visa', 'mastercard', 'amex', 'jcb',
                        'diners', 'discover', 'mir', 'unionpay'],
    supportedTypes: ['credit', 'debit']

var details = { ... };

var options = { ... };

var request = new PaymentRequest(supportedInstruments, details, options);


This feature is no longer part of any specification.
