Biometric device and means for electronic storage and retrieval of biometric data

摘要

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.

主权项

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; andiv) 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.
