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

The biometric device of claim M, wherein said chemical treatment of the chemically treated cellulose fibre based matrix is the application of one or more of:

• i) a weak alkali;
• ii) a chelating agent;
• iii) an anionic surfactant or detergent;
• and
• iv) uric acid or a urate salt.

A storage system for storing plurality of biometric devices each containing biological material, the system comprising:

• a) bringing together a plurality of biometric devices, each 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 (RF) communication and including writable data storage;
• b) housing each device in spaced relation;
• and
• c) identifying one or more of said housed devices by means of interrogating its associated circuit using RF communication.

A method for the processing of 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 (for example rewritable) data storage, 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.
