qr code

qr code

I would like to add a unique QR code to my pre-printed deposit slips.  The QR code would go to a form that allows my employee to enter the deposit info. The question I have is, can I create a QR code that is unique to each deposit slip? And is there a way to scan the QR code twice? First scan for the employee to enter the info and the second for me to verify/approve the deposit.
