在PHP中处理数字指纹

Question

Is there any interface or php library that can autenticate users by their fingerprint.

• Any software that php can use to do this?

• Any hardware that can be used for this?

Answer 1

PHP is almost certainly the wrong solution to this problem. PHP has no easy way to interface with hardware unless you're prepared to write an extension in a low-level programming language. (It's hard to capture fingerprints without, say, the hardware to scan them in.)

You best bet is going to be asking the manufacturer of your fingerprint scanner of choice about their recommended way to interface with it. If you don't have the hardware, you're probably out of luck here on SO.
