Abstract
A proxy card comprising a swipe speed sensor that detects the speed at which the proxy card is traveling through a magnetic card reader and a microcontroller that uses the swipe speed to adjust a rate at which magnetic stripe data stored in a memory on the proxy card is transmitted to a magnetic stripe emulator on the proxy card is disclosed. The magnetic stripe emulator emulates the magnetic stripe data by generating a magnetic field that changes at the rate at which the magnetic stripe data is received from the microcontroller to ensure that the changing magnetic field is readable by a magnetic stripe reader in the time it takes to complete the swipe. The rate at which the magnetic stripe data is transmitted to the magnetic stripe emulator can be a predetermined multiple of the swipe speed of the proxy card.
