I have this payroll project where my client wants to use biometrics to easily keep track the time attendances of his 400 employees. However, the problem is his company has a high employee turnover rate. It implies that the biometrics fingerprint scanner which usually has only a limited number of available fingerprint templates from 1000 to 2000, the biometrics may eventually run out of memory.
The better solution I can think of is to use the payroll system directly as the data store for the biometrics fingerprint scanner. However, I can't seem to find any biometrics fingerprint scanner that allows to send raw biometrics data to the computer for storage.
Is there a biometrics scanner available in the market where it offers an SDK which allows developers to interface the scanner directly to the software so that it can be used as a large data store?
