I am planning to borrow room keys or tickets for public transport in a rehabilitation clinic. The basic configuration of a tracker and the linking of trackers (patient, key number and ID of the ticket) are no problem. Now to the question:
I would like the borrower to confirm receipt of the key with a signature on a touch screen on a Rasberry Pi. The image of the signature should be imported into the corresponding tracker entry as automatically as possible. We use key chips in the house, perhaps confirmation by placing a chip on a reader would also be possible.
Does anyone have an idea how this could be implemented?
Service personnel and the hirer do not work on the same machine! I sit behind the reception and the lender only has the touch screen at his disposal.
Otherwise the Ras Pi serves as a kiosk system.
