How to reprogram this NFC reader? Answered
So I've got this NFC mobile banking from work (we've shut down the system because of lack of users) and we were left with a few hundred of these "read-write" NFC things. As you can see from the photos they have 2 SIM-card holders (probably that is the way they were connecting to the network) 2 USB mini ports, a RGB screen, a small speaker, and the board which is made of 2 easily disconnected parts. If I try to connect it to my PC it gets stuck on "Time and date set" and after a minute it writes a "Failed" on the screen. What i want to do is to make it able to read/write NFC chips and to display text on the display. Please help me because I have no idea hot to do this.
