    Arduino Tutorials – RFID

    You need to add a new variable tag3 for instance, then put the tag id in the same way the other two are inserted! Now you need to change the check_cards function to also check if the card could be card number three!Do you need more detail?

    First disable your Capslock as it´s a form of shouting online!There are a few ways to your problem.1. Have a boolean that is true only when you have swiped a "good" rfid card.2. Wire the vcc pin of your keypad to a gpio pin of the arduino and hold that up for a given time frame.3. Use your code structure in your loop(){} you just check for RFID Cards if there is one and the ID is correct then you proceed and read the keypad values (it´s similar to version 1) if the card is not correct you just proceed to read for rfid cards... Make sure you deactivate the read of the keypad after the right code was entered(or after a given period of time)
