Biometric identification system
First Claim
1. A biometric identification system, comprising:
- an identification device comprising a radio frequency identification (RFID) element storing a first set of biometric information; and
an identification system comprising a communication device using radio frequency signals to read the first set of biometric information from the identification device when the identification device is proximal to the identification system, a biometric reader reading a second set of biometric information from an individual, and a comparison mechanism comparing the first set of biometric information to the second set of biometric information to determine if the two sets of biometric information are a match.

Abstract
A biometric identification system that includes one or more identification devices or cards. Each identification card includes a radio frequency identification (RFID) element storing a first set of biometric information. A communication device operates to send and receive radio frequency signals to read the first set of biometric information from the identification device when they are proximal to each other but without insertion or physical contact. A biometric reader is provided that reads a second set of biometric information from an individual presenting the identification card. A comparison mechanism compares the first and second sets of biometric information to determine if the two sets are a match. When no match is found, a flag mechanism modifies a value of a flag in the RFID element of the identification device. An update mechanism determines when the match exceeds an accuracy limit and updates biometric information on the identification device wirelessly.

7. A radio frequency biometric identification system, comprising:
-
a biometric reader reading biometric information from an individual based on scanning a physical feature of the individual;
a data writer formatting the read biometric information and with radio frequency signals writing the formatted biometric information to a radio frequency identification (RFID) tag provided on an identification device; and
a comparison mechanism comparing a set of read biometric information from the biometric reader matches a set of biometric information obtained from the identification device. - View Dependent Claims (8, 9, 10, 11)

12. A biometric identification method, comprising:
-
activating a biometric identification card including first scanning a biometric feature of a person and writing biometric information from the scanning into a radio frequency identification (RFID) element embedded in the biometric identification card;
without insertion or contact, reading the biometric information from the RFID element;
second scanning a biometric feature of a person presenting the biometric identification card as part of an access transaction to obtain a comparison set of biometric information; and
determining whether the comparison set of biometric information is a match of the read biometric information from the RFID element of the biometric identification card. - View Dependent Claims (13, 14, 15)
