Abstract
A method and apparatus for secure authentication of Near Field Communication transactions based on proximity to a mobile key device.
Claims20
A method for authorizing a Near Field communication (NFC) payment transaction comprising the steps of
- establishing a two-way secure wireless connection between a first mobile device having an NFC function and a second mobile device,
- wherein said second mobile device comprises a short wireless transceiver,
- wherein said second mobile device has a size smaller than 22.5 cubic centimeter,
- wherein said second mobile device can pair with a compatible apparatus within proximity, and upon pairing with a compatible apparatus, said second mobile device changes mode to a non-discoverable mode,
- wherein said second mobile device can store user data selected from the group consisting of
- a credit amount, a credit limit, a threshold, a maximum transaction amount, an amount, a digital key;
- wherein upon receiving a request for authenticating an NFC payment transaction,
- said first mobile device will send a request to said second mobile device,
- wherein said first mobile device will authorize the NFC payment transaction if it receives a response from said second mobile device that enables said first mobile device to authorize the NFC payment transaction.

A method for automatically authorizing a Near Field Communication (NFC) payment transaction comprising
- executing an NFC application on a first mobile device,
- establishing a two-way secure short wireless connection between said first mobile device and a second mobile device comprising a short wireless transceiver,
- wherein said second mobile device has a size smaller than 22.5 cubic centimeter,
- wherein said second mobile device can pair wirelessly with a compatible apparatus within proximity,
- wherein upon pairing with said first mobile device, said second mobile device changes to a non-discoverable mode,
- wherein said second mobile device can connect to a programming device and can store user data obtained from said programming device in flash memory onboard said second mobile device,
- wherein upon receiving a request for authenticating an NFC payment transaction,
- said first mobile device will send a first request to said second mobile device through a short wireless means,
- wherein upon receipt of a first response from said second mobile device,
- said first mobile device will send a second request to a remote server through a protocol selected from the group consisting of
- GPRS, SMS, USSD;
- wherein upon receipt of a second response from said remote server,
- said first mobile device will authorize said NFC payment transaction if said second response enables the first mobile device to authorize said NFC payment transaction.

- wherein said user data is selected from the group consisting of a credit amount, a credit limit, a threshold, an amount, a digital key, an encryption key;
- wherein said unitary mobile apparatus has a size smaller than 22.5 cubic centimeter,
- wherein said unitary mobile apparatus can pair with a first mobile device within proximity,
- wherein upon pairing with said first mobile device, said unitary mobile apparatus can switch to a non-discoverable mode,
- wherein upon receipt of a message from said first mobile device for authorizing an NFC payment transaction,
- said unitary mobile apparatus can send a reply to said first mobile device,
- said first mobile device can authorize or deny said NFC payment transaction.
