Agree that that check cashing machines can save labor costs, but the camera based software is too costly and time consuming - a fingerprint scanner (see Business Week) can be attached to ATM's, Checkcashing Machines, etc. What I am saying is that the software out there now, and in the pipeline will leapfrog the Mr. Payroll machine technology. The machine may not be dead, but a drastic rework will be needed. Living in the Silicon Valley, I have seen this happen often - great product, but short life-span.
What happens if the fingerprint can't be read or the software makes a mistake? Can a person analyze the fingerprint like they can the picture? Also, the value of the machine is not the biometric used but rather the back-end solution and assumption of risk. C-ya.
