Recognition only
This option will suit you if your mobile app needs only to get a card number from Pay.Cards. For example in case you are not charging from bank card and plan to use your own gateways for transactions.
Recognition and payment acceptance
If you are not willing to integrate with banks by yourself to charge user’s bank cads, you may use this version of SDK. In this case you just need to transmit to Pay.Cards an amount and a currency of an invoice. As a result you will get a status of a bank transfer.
