RFID with Bio-Smart Card in Linux
In this paper, we describe the integration of fingerprint template
and RF smart card for clustered network, which is designed on Linux
platform and Open source technology to obtain biometrics security.
Combination of smart card and biometrics has achieved in two step
authentication where smart card authentication is based on a
Personal Identification Number (PIN) and the card holder is
authenticated using the biometrics template stored in the smart
card that is based on the fingerprint verification. The fingerprint
verification has to be executed on central host server for
security purposes. Protocol designed allows controlling entire
parameters of smart security controller like PIN options, Reader
delay, real-time clock, alarm option and cardholder access
conditions.

Packet Sniffing Overview
The best way to secure you against sniffing is to use encryption.
While this won't prevent a sniffer from functioning, it will ensure
that what a sniffer reads is pure junk.
