Abstract
Dynamic magnetic stripe communications devices are provided as magnetic stripe emulators. A device, such as an application specific integrated circuit, may include a waveform generator that retrieves data from memory and may generate waveforms from the retrieved data to be communicated by the magnetic stripe emulator and received by a magnetic stripe reader.
Claims20
A device comprising:
- a magnetic stripe emulator operable to communicate an analog waveform encoded with at least one track of magnetic stripe data to a magnetic stripe reader;
- and
- a waveform generator operable to generate said analog waveform from a digital representation of said at least one track of magnetic stripe data,
- wherein said device is operable to retrieve said digital representation from a plurality of digital representations of said at least one track of magnetic stripe data.
1 more element
A system, comprising:
- a card including,
- a magnetic stripe emulator operable to communicate an analog waveform encoded with at least one track of magnetic stripe data, and
- a programming interface;
- and
- a programming device operable to communicate data to said programming interface, said data including multiple representations of said at least one track of magnetic stripe data.
2 more elements
A method, comprising:
- selecting a payment account associated with a payment card;
- selecting one of a plurality of digital representations of said selected payment account from a memory of said payment card;
- converting said digital representation to an analog waveform;
- and
- communicating said analog waveform from said payment card to complete a purchase transaction.
