Wearable device transaction system
View Patent ↗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.
1. A transaction system comprising:
a wearable device having an add-on slot to accept an electronic transaction card; and
an electronic transaction card with smartcard circuitry and circuitry coupled to the smartcard circuitry to produce a time varying magnetic field, wherein the circuitry to produce a time varying magnetic field has dimensions less than 25% of a standard credit card, the electronic transaction card including an interface compatible with the add-on slot of the wearable device.
2. The transaction system of claim 1 wherein the wearable device comprises a wristwatch.
3. The transaction system of claim 1 wherein the wearable device comprises a wearable device that when worn contacts human skin.
4. The transaction system of claim 1 wherein the wearable device comprises a wearable device that is worn on clothing.
5. The transaction system of claim 1 wherein the interface compatible with the add-on slot of the wearable device comprises a memory card interface.
6. The transaction system of claim 1 wherein the electronic transaction card is compatible with a smartcard reader.
7. The transaction system of claim 1 wherein the electronic transaction card further comprises a point-of sale interface coupled to the smartcard circuitry.
8. The transaction system of claim 1 wherein the electronic transaction system is configured to perform transactions.
9. The transaction system of claim 8 wherein the transactions are financial transactions.
10. The transaction system of claim 8 wherein the electronic transaction card is configured to operate as a credit card.
11. A transaction system comprising:
a wearable device having contacts to communicate with an electronic transaction card; and
an electronic transaction card having contacts coupled to the contacts on the wearable device, the electronic transaction card including smartcard circuitry for performing contactless transactions and circuitry coupled to the smartcard circuitry to produce a time varying magnetic field, wherein the circuitry to produce a time varying magnetic field has dimensions less than 25% of a standard credit card.
12. The transaction system of claim 11 wherein the wearable device comprises a wristwatch.
13. The transaction system of claim 11 wherein the wearable device comprises a wearable device that when worn contacts human skin.
14. The transaction system of claim 11 wherein the wearable device comprises a wearable device that is worn on clothing.
15. The transaction system of claim 11 wherein the smartcard circuitry is configured to perform point-of-sale transactions.
16. The transaction system of claim 11 wherein the transactions are financial transactions.
17. The transaction system of claim 11 wherein the electronic transaction card is configured to operate as a credit card.
