Fingerprint using Arduino, PHP and MySql

I'm doing a project with fingerprint using Arduino, PHP and MySql. Actually, i'm registering the finger ID in the equipment memory and i use this same ID in my data base as the Biometric of the person. So, i depended of the equipment memory and it is not good, because if the equipment spoil i'll lose all the data. I would like to save not the id, but the biometric code direct in my data base. Is it possible? I don't know how it work, if it generate a image, and a code of the image. Can somebody help me?
