Method, systems, and apparatus for processing a payment transaction includes determining that a network connection between a first destination in a payment system and a second destination in a payment system does not satisfy a latency threshold; receiving data indicating a payment transaction between a customer and a merchant; determining whether the payment transaction should be stored, where the determining is based on a risk algorithm model that considers risk factors associated with data regarding the payment transaction, risk factors associated with data regarding the customer, and risk factors associated with data regarding the merchant; if the payment transaction should be stored: storing the payment transaction for future processing; displaying an indication that the payment transaction has been successfully processed; if the payment transaction should not be stored: attempting to send a request for authorization for the payment transaction at a payment service system included in the payment system.

One variation of a method for controlling a dynamic transaction card includes: at a first time, accessing a first cryptogram; at a second time, establishing a wireless connection with a mobile computing device; in response to establishing the wireless connection with the mobile computing device, accessing a first token associated with the first cryptogram from the mobile computing device via the wireless connection; generating a first magnetic stripe sequence command representing the first cryptogram and the first token; and in response to detecting a magnetic stripe card reader proximal a magnetic stripe emulator integrated into the dynamic transaction card at a third time succeeding the second time, driving the magnetic stripe emulator according to the first magnetic stripe sequence command.

A payment terminal may receive a request to process electronic payment information from a payment card in a swipe mode. The payment terminal may provide an opt-in request. If a user accepts, the payment terminal may receive a payment transaction request and electronic payment information of a swipe payment type from the payment card at a swipe interface. The payment terminal may determine whether the payment card is a chip card and generate a swipe mode processing indicator. The swipe mode indicator may allow processing of electronic payment information using procedures for the swipe payment type. The payment terminal may transmit the swipe mode processing indicator and electronic payment information to a payment server from a communication interface of the payment terminal, and may receive a payment approval response based on the swipe mode processing indicator.

Systems, methods, and computer-readable media for chopping up a gift card/code into smaller multiple gift card/codes. The system receives a request from a user to convert a closed-loop card/code having a value amount into two different closed-loop cards/codes and divides (or chops up) the closed-loop card/code into a first closed-loop card/code having a first value amount and a second closed-loop card/code having a second value amount, wherein the first value amount and the second value amount add up to no more than the value amount. The system offers the first closed-loop card/code and the second closed-loop card/code to one of the user and a third party.

A method is disclosed. The method includes receiving a first session key different from a Master Key from a remote entity, the first session key based on the Master Key. The first session key is usable for a limited number of transactions. In response to receiving the first session key, the method includes provisioning a payment application in the user device with the first session key. The method includes receiving, at the payment application, a request for an application cryptogram from a point-of-sale terminal. In response to the receiving the request for the application cryptogram, the method includes generating the application cryptogram using the first session key, transmitting the application cryptogram to the point-of-sale terminal, and receiving a second session key from the remote entity. The second session key is based on the Master Key.
