What's better than RFID tags? Your own fingerprints, of course. No batteries needed, no electronic eavesdropping devices, and no storage problems. They're always convenient and, well, they're always at your fingertips. The only problem with using fingerprint biometric controls is finding a suitable fingerprint reader. And, no, we're not talking about that archaic monstrosity used at the local cop shop, either. We're talking about an small, inexpensive fingerprint reader that just needs a swipe of your precious digit for unleashing a torrent of programming power.
