cardless checkin

I've never been to a gym that used cardless checkin.

But recently, our 24 Hour Fitness Clubs began using a cardless checkin program. You use an id number, like a phone number, and then scan your index finger. Now this seems a little "Big Brother" to me, so I checked out what the company has to say about it. According to their website, your actual fingerprint is not kept on file. Using biomechnic techniques, they scan distinct points on your fingerprint that are unique to you.  Then an id number is devised based on those distances of your print. They keep no fingerprints on file nor can your print be replicated.


 That I'd like to see.
