'Biometrics and making Transactions`'

Kyndra from Somewhere Out There -

Maybe we should rid of pin numbers and signatures when it comes to debit/credit cards. Why can't they set up something where you can just use your thumbprint to verify a transaction. That is something that can not be stolen or duplicated.

Comment #1 Elroy from New York -

"can not be stolen or duplicated" why not?

"why not" is especially true if you are talking about a remote scanner on a computer... like at a restaurant... when the client "signs" his check with this thumb, record the print and the card number and make purchases with the info later.

Comment #2 Lana from The Dental Office -

It seems like it would be a little harder to duplicate a finger print to use and what if the scanner also has to detect body heat or something to that degree? I think it is a better idea than a pin number. Plus mail gets mixed up and stolen so people can steal pin numbers.

Comment #3 Elroy from New York -

Once your finger print is scanned, it is no longer a biometric. It is a binary code. Some where a computer decides if that binary code matches another binary code.

If either binary code (the scanned one, the stored one), or the system that matches them can be compromised, the whole system is compromised.

Imagine a finger print scanner than not only scans, but records and later lets you select which one to retransmit.

Think it this way. Which is more likley to to be stolen and dulipicated. Your fingerprints, or your PIN number etc? Which would require more effort?

I personally would kind of feel uncomfortable with the system having my fingerprints, but if it meant it'd be harder for people to steal my information, that would be nice but I am unsure if it would work this way.

TODAY:

Your fingerprints, or your PIN number etc?

PIN

IN THE FUTURE:

Your fingerprints, or your PIN number etc?

FINGERPRINTS.

Why?

Because TODAY systems are base on PIN. In the future when they are based on fingerprints, that is what will be stolen.

Which would require more effort?

That dosen't matter. What matters is the usefulness.
