Biometric device and means for electronic storage and retrieval of biometric data
There is disclosed a biometric device ( 10 ), comprising a solid support ( 14 ) suitable for receiving biological material (S) and for dry storing that material at room temperature the device further comprising a circuit ( 16 ) including means for two way radio frequency communication and including writable data storage. Also disclosed is a processing method for such biometric devices, the method including the steps of: a) identifying said device by means of RF communication; b) extracting at least a portion of the biological material from the solid support of the identified device; c) analyzing the extracted biological material to obtain biometric data indicative of the biological material; and d) writing said biometric data to the data storage of the biometric device.
1. A biometric information storage device comprising:
a foldable card support comprising a first region, a second region, and a third region, wherein a first fold in the card support separates the first region from the second region, and wherein a second fold in the card support separates the second region from the third region,
wherein the first region comprises a solid support configured to receive a biological sample, dry store the biological sample at room temperature, and allow retrieval of the biological sample therefrom, and wherein the solid support is a cellulose-based paper matrix chemically treated with:
i) a weak alkali;
ii) a chelating agent;
iii) an anionic surfactant or detergent; and
iv) uric acid or a urate salt;
wherein the second region comprises a radio frequency identification (RFID) tag arranged to provide two-way communication and store biometric information in non-volatile memory, and
wherein the foldable card support is configured to be folded such that the third region can at least partially cover the first region and protect a biological sample from contamination when disposed on the solid support.
2. The biometric device of claim 1 , wherein the non-volatile memory is rewritable.
3. The biometric device of claim 1 , wherein a biological sample is disposed on the solid support, wherein the RFID tag has stored therein personal information relating to a person from which the biological sample is derived, and wherein the RFID tag has stored therein data indicative of the biological sample.
