SYSTEMS AND METHODS FOR PERFORMING SECURE IN-PERSON TRANSACTIONS
First Claim
1. A handheld device for facilitating secure transactions, the handheld device comprising:
- rewritable radio frequency identification (RFID) circuitry;
a biometric sensor configured to receive user identification information;
a memory configured to store transaction information;
a processor coupled to the memory and the biometric sensor, the processor being configured to authenticate the user identification information and to temporarily write the transaction information to the rewritable RFID circuitry upon authentication of the user identification information, the transaction information being readable from the RFID circuitry by an external reader.

Abstract
A portable, biometrically-secured device for facilitating various different types of in-person and online transactions. For example, the portable, biometrically-secured device can be used to safely perform in-person financial transactions, such as credit card transactions, in which the user'"'"'s identity is biometrically authenticated. The portable, biometrically-secured device can also be used for performing biometrically-secured online transactions. For example, the portable, biometrically-secured device can be used to create a secure platform from which to make the online transactions by loading a secure operating system from the device to a host computer'"'"'s volatile memory. Biometrically-secured online transactions can then be performed using the host computer. In one embodiment, the portable, biometrically-secured device facilitates online financial transactions that can be performed without transmitting a user'"'"'s financial information to the online merchant.

12. A method of performing a secure transaction, the method comprising:
-
receiving biometric information from a user;
determining whether the biometric information corresponds to a stored biometric signature;
writing transaction information to a rewritable radio frequency identification (RFID) tag when the biometric information corresponds to the stored biometric signature;
transmitting the transaction information; and
removing the transaction information from the rewritable RFID tag after transmitting the transaction information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
