Biometric device and means for electronic storage and retrieval of biometric data
A biometric device, comprising a solid support suitable for receiving biological material and for dry storing that material at room temperature the device further comprising a circuit including means for two way radio frequency communication and including writable data storage. 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) analysing 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 method for processing a biometric device comprising:
providing a first biometric device comprising: a support configured to receive a biological sample, dry store the biological sample at room temperature, and allow retrieval of the biological sample therefrom; and a radio frequency identification (RFID) tag arranged to provide two-way radio communication and store biometric information in a data storage of the first biometric device, wherein the support of the first biometric device is a foldable card support;
identifying the first biometric device by radio frequency communication;
extracting a first biological material from the support of the first biometric device to yield a first biological material extract;
analyzing the first biological material extract to obtain first biometric data indicative of the first biological material; and
writing the first biometric data to the data storage of the first biometric device.
2. The method of claim 1 , further comprising writing personal information about a provider of the first biological material to the data storage of the first biometric device.
3. The method of claim 1 , wherein the extracting step comprises amplifying a nucleic acid, detecting a protein, or both.
4. The method of claim 1 , wherein the extracting step comprises amplifying a DNA, a RNA, an oligonucleotide, or a combination thereof.
5. The method of claim 1 , wherein the extracting step comprises amplifying a nucleic acid by polymerase chain reaction (PCR).
6. The method of claim 5 , wherein the PCR comprises combining a dried reagent mixture comprising PCR reaction components or a glassy porous sphere comprising PCR reaction components with a sequestrant.
7. The method of claim 5 , wherein the PCR is reverse transcriptase polymerase chain reaction (RT-PCR).
8. The method of claim 1 , further comprising:
identifying, for a second time, the first biometric device by radio frequency communication;
extracting a second biological material from the support of the first biometric device to yield a second biological material extract;
analyzing the second biological material extract to obtain second biometric data indicative of the second biological material; and
writing the second biometric data to the data storage of the first biometric device.
9. The method of claim 8 , further comprising:
comparing the first biometric data to the second biometric data to determine whether the first biological material and the second biological material are from a same individual.
10. The method of claim 1 , further comprising:
providing a second biometric device comprising: a second support configured to receive a second biological sample, dry store the second biological sample at room temperature, and allow retrieval of the second biological sample therefrom; and a second radio frequency identification (RFID) tag arranged to provide two-way radio communication and store biometric information in a second data storage of the second biometric device.
11. The method of claim 10 , further comprising:
identifying the second biometric device by radio frequency communication;
extracting a second biological material from the second support of the second biometric device to yield a second biological material extract;
analyzing the second biological material extract to obtain second biometric data indicative of the second biological material; and
writing the second biometric data to the data storage of the second biometric device.
12. The method of claim 11 , further comprising:
comparing the first biometric data to the second biometric data to determine whether the first biological material and the second biological material are from a same individual.
13. The method of claim 1 , wherein the data storage of the first biometric device is non-volatile memory.
14. The method of claim 1 , wherein the data storage of the first biometric device is rewritable.
15. The method of claim 1 , wherein the support of the first biometric device is a matrix made from cellulose fibers, nitrocellulose, nylon, or polyvinylidene fluoride.
16. The method of claim 1 , wherein the support of the first biometric device is a matrix chemically treated with a weak alkali; a chelating agent; an anionic surfactant or detergent; and uric acid or a urate salt.
17. The method of claim 1 , wherein the support of the first biometric device comprises an electrically conductive path connected to the radio frequency identification tag of the first biometric device which is breakable by a user.
