BioLink FS25 USB2.0

Biolink’s FS25 USB2.0 Fingerprint Mifare Card Reader/Writer combines a fingerprint scanner and an ISO14443A compatible Mifare card Reader/Writer into one device.

FS25 is a standalone fingerprint matcher and can do “Match on Device”. Under the control of PC via USB interface, it captures a fingerprint image, extracts the minutiae (fingerprint characteristics) and then stores to its internal memory. The stored fingerprint can be used to match with a freshly captured fingerprint and matching result is sent to PC for authentication. Its internal memory can store up 100 fingerprints.

With a combination of fingerprint “Match on Device” and ISO14443A Mifare card Reader/Writer, FS25 is perfect for real two-factors authentication, what you own(finger) is matched with what you carry(Mifare card). It is because fingerprint data can be stored to Mifare card and at the time of authentication:

• User shows the Mifare card and FS25 read the fingerprint data stored in card.
• Then put finger and FS25 scans the fingerprint image.
• FS25 matches the scanned fingerprint with the fingerprint data read from the Mifare card.
• The matching result is sent to PC for authentication

The use of fingerprint recognition for logical and physical access control has been controversial. It is because the fingerprint data must be stored somewhere in system for authentication. This may infringe the privacy of users in some cases. And FS25 is the answer to this problem as it can identify an individual using fingerprint without storage of fingerprint data in the system.
