Thanks for reminding me people need to be educated about this.
All the stuff you were talking about is using your actual fingerprint. What happens is they use the actual ink-created fingerprint or a very high resolution digital image of it and compare it to the FBI's AFIS (Automated Fingerprint Identification System) as part of a criminal background check. That is necessary when you want to make sure someone isn't a criminal. I've had to have it done as well since I work with a youth group. It has a place.
But biometric verification works differently. First of all, the digital camera used is very low resolution and would never come close to to the AFIS standard. Secondly, the camera doesn't really look at your fingerprint, per se. What it does is look at a certain number of points on your fingerprint (usually between 5-10 points) and looks to see if there is a hill or valley on that specific point. It takes those data points and converts it to a number. That number is the only thing stored or compared to the database when it is being checked.
On these systems, they say there is a 1 in a 1000 chance two people will have the same "fingerprint" (really a number). But when coupled with a photo ID, it gives you a very high comfort level that the person is who they are claiming to be and that the photo ID hasn't been faked.
In the two places I worked when this system was implemented, involving probably 10,000 employees, I think there were 3-4 that said there was no way they were going to do it. After I talked to them and gave them information from our vendor about how it worked, all of them had no problems with it after they were educated on the process. It's really a simple system that has been hashed out over about 20 years and it works very well.
