So much for the days of anonymous one-night stands with girls.
On the other hand, building access could suddenly become a lot cooler. Touch the pad, and not only could they fingerprint ID you, but they could check the MD5 hash of your PDA. Or something. I'm just babbling again.
Edit - 0roo, we already have data communication through b00bies. It's IR-based though, so it only works on line-of-sight.
b00bies: "Touch me."
Guy: "Okay."
Experimental studies have shown the ping time of such communication to be nearly instantaneous (less than 2ms), and removing clothing further reduces the response time. For optimal bandwidth, however, full physical contact is recommended.
