ABSTRACT:
A wireless fingerprint attendance system comprises at least one fingerprint scanner and a computer server. First templates of fingerprint related data are stored on the server, and similar templates are stored on the scanner. When a fingerprint is scanned, the fingerprint data is transmitted wirelessly to the server, where a comparison is made. The server directs the scanner to display an indication whether or not a match was found. If available, an updated list of templates of fingerprint related data is transmitted from the server to the scanner and is added to the first templates. If a connection is not made, the scanned data remains on the scanner, which makes the comparison using the scanner templates. At periodic intervals the scanner and server attempt to connect. At a successful connection, the scanned fingerprint data is wirelessly transmitted to the server, and the scanned fingerprint data is purged from the scanner.
