Abstract
Methods and apparatus for enabling a proximity payment device to generate dynamic data for securely conducting a transaction by emulating a magnetic stripe payment card. In an embodiment, a mobile device processor transmits information to a digital enablement service computer to activate a simulated magnetic stripe payment wallet application stored in the mobile device. The mobile device then receives one or more cryptographic keys, generates an unpredictable number (UN), generates dynamic CVC3 data based on the UN, and then assembles emulated magnetic stripe data. During initiation of a purchase transaction, the mobile device processor transmits the emulated magnetic stripe data to a communications interface associated with a merchant device.
