I have a question about the RFID MFRC522 project with two LED lights. If I scan with the RFID tag or card and I continuously hold my bag over the laser, it keeps scanning and you see the green and red LED lighting flashing back and forth.
Now if I do not place the badge over the laser, the LED light should glow red (this works) and if it remains constantly over the laser, the LED light should remain glowing green so that it only scans the ID once. (So it has to scan once when it is on it + green light, when I take it away the red light must remain on).
Is there no way to save the data in memory so that it continues to remember the ID and which code should I use for this?
