Wearable device with current carrying conductor to produce time-varying magnetic field
First Claim
Patent Images
1. A wearable device comprising:
- a memory to hold a transaction number; and
a conductor that when excited by a time-varying current produces a time-varying magnetic field that emanates from the wearable device and 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.

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.
