Abstract

A biometrically activated radio frequency identification (RFID) tag including a fingerprint detection matrix, an antenna control circuit, and a biometric identification chip. The fingerprint detection matrix acquires biometric data indicative of a user'"'"'s identity and passes it to the biometric identification chip. The biometric identification chip compares the biometric data acquired by the fingerprint detection matrix to biometric data stored thereupon. The antenna control circuit activates the RFID tag selectively dependent upon the result of the comparison of the acquired and stored biometric data.

Claims

1. A method of activating a radio frequency identification (RFID) tag, comprising:

acquiring biometric data indicative of an identity of a user at the RFID tag,

wherein the acquired biometric data comprises fingerprint biometric data, the acquiring including;

scanning the fingerprint biometric data at the RFID tag,

wherein the scanning includes placing a finger of the user over a fingerprint sensor of the RFID tag;

comparing the acquired biometric data with biometric data of an authorised user at the RFID tag, the biometric data of the authorised user stored at the RFID tag;

activating the RFID tag in the case that the acquired biometric data matches the biometric data of the authorised user,

wherein the activating occurs only during simultaneously placing the RFID tag within an operational distance from an interrogator during the placing of the finger of the user over the fingerprint sensor;

deactivating the RFID tag between successive scans of the finger of the user while the finger of the user remains on the fingerprint sensor of the RFID tag; and

transmitting information prompting display of the user'"'"'s personal information on a display external to the RFID tag immediately after activating the RFID tag.

2. The method of claim 1, further comprising:

selectively enabling an antenna of the RFID tag to selectively activate the RFID tag.

3. The method of claim 1, further comprising:

providing the biometric data of the authorised user to the RFID tag; and

storing the biometric data of the authorised user on the RFID tag.

4. The method of claim 3, further comprising:

providing the biometric data of the authorised user by downloading the biometric data of the authorised user to the RFID tag.

5. A biometrically activated radio frequency identification (RFID) tag, comprising:

a biometric sensor arranged to acquire biometric data indicative of an identity of a user at the RFID tag,

wherein the acquired biometric data comprises fingerprint biometric data, the acquiring including;

scanning the fingerprint biometric data at the RFID tag,

wherein the scanning includes placing a finger of the user over a fingerprint sensor of the RFID tag;

a processing component arranged to;

control an activation and deactivation of the biometrically activated RFID tag by comparing the acquired biometric data with biometric data of an authorised user stored at the RFID tag;

activate the RFID tag in the case that the acquired biometric data matches the biometric data of the authorized user,

wherein the activating occurs only during simultaneously placing the RFID tag within an operational distance from an interrogator during the placing of the finger of the user over the fingerprint sensor; and

deactivating the RFID tag between successive scans of the finger of the user while the finger of the user remains on the fingerprint sensor of the RFID tag; and

an antenna arranged to transmit information prompting display of the user'"'"'s personal information on a display external to the RFID tag immediately after activating the RFID tag.

6. The RFID tag according to claim 5, wherein the biometric sensor is provided on the RFID tag.

7. The RFID tag according to claim 5, further comprising:

a storage component arranged to store the biometric data of the authorised user on the RFID tag.

8. The RFID tag according to claim 5, wherein the processing component is further arranged to disable or enable the antenna of the RFID tag to selectively activate the RFID tag.

9. The RFID tag according to claim 5, wherein the processing component further comprises:

an RFID chip arranged to selectively activate or deactivate the RFID tag.

10. A computer program for activating a radio frequency identification (RFID) tag when the computer program is executed on a computer system stored in a computer readable storage medium, the computer program comprising program code for:

acquiring biometric data indicative of an identity of a user at the RFID tag,

wherein the acquiring includes;

scanning the biometric data indicative of the identity of the user at the RFID tag,

wherein the scanning includes placing a finger of the user over a fingerprint sensor of the RFID tag;

comparing the acquired biometric data with biometric data of an authorised user at the RFID tag, the biometric data of the authorised user stored at the RFID tag;

activating the RFID tag in the case that the acquired biometric data matches the biometric data of the authorised user,

wherein the activating occurs only during simultaneously placing the RFID tag within an operational distance from an interrogator during the placing of the finger of the user over the fingerprint sensor;

deactivating the RFID tag between successive scans of the finger of the user while the finger of the user remains on the fingerprint sensor of the RFID tag; and

transmitting information prompting display of the user'"'"'s personal information on a display external to the RFID tag immediately after activating the RFID tag.
