Method for encrypting transactions at a dynamic transaction card

Abstract

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.
