Abstract
An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.
Claims18
A method performed by a wearable device, the method comprising:
- receiving a communication over a network;
- and
- in response to the communication, programming circuitry in the wearable device to drive a conductor with a time-varying current to produce a time-varying magnetic field that emulates a swipe of a magnetic card, wherein the time-varying magnetic field represents a transaction number and the transaction number is used repeatedly for each emission of the time-varying magnetic field to emulate the swipe of the magnetic card.
A method performed by a wearable device, the method comprising:
- receiving a communication over a network;
- in response to the communication, programming a memory in the wearable device with a transaction number;
- and
- driving a conductor with a time-varying current to produce a time-varying magnetic field that emulates a swipe of a magnetic card, wherein the time-varying magnetic field represents the transaction number and the transaction number is used repeatedly for each emission of the time-varying magnetic field to emulate the swipe of the magnetic card.
