I'm currently looking into doing a project involving the raspberry pi and a few pieces of hardware.
Description of Project : This program would require users to select an item from a list and after which, type in a number. Basically select a fruit and type in the quantity for example.
After which, there would be user authentication done using the fingerprint reader. The user would scan his fingerprint on the reader and if verified successfully, we can proceed to make the "order". With this piece of information, a QR code will be generated and will be printed out on a label printer.
Currently I have access to a RAspberry PI 2 Model b and Fingerprint Scanner - TTL (GT-511C3). I just need help up to the part where the QR code will be generated.
