How to Read Text From an NFC Card

Projects General Guidance
1

I'm currently working on a project that uses NFC cards to trigger different actions. To do this, I need to read data that I've stored on the NFC card using the NFC Tools app on my phone.

My plan is to store numbers on the card and perform specific actions depending on the number. I'm using the PN532 module, but none of the example codes I've found seem to do what I need.

I don't have much coding experience, so I'm not sure how to proceed.

So, here's my question:
What is the easiest way to read a number or text written on an NFC card (using NFC Tools) with the PN532 module?

I'm currently using the SPI configuration, but I'm open to using I2C if it's easier.

What controller are You using and for what controller are the tested codes written?

Can You define the limits for Good, Better, the Best?

Im sorry i dont understand what you mean by controller? do you mean the Library or the Module? Im Using Adafruit_PN532 library if that is what you mean

4

which board do you have connected to the reader? Is is an ardunio UNO? a Nano? some flavor of esp32? That is a controller.

Did you try any of the examples that come with that library? the basic readMiFare.ino example reads and writes to the tag. I'd start with getting that working and then see if your phone app can see the data or not.

Which microcontroller board are You using? Arduino UNO, Arduino Mega, Arduino Micro, ESP....?

Oh Sorry for that, I am using a bootleg arduino Nano

7

Sorry for that its a bootleg Arduino Nano, ive tried most of the examples the library offers

Ill try that example and get back here

Hey Thanks It Worked, Now i Get the Data I need to continue my project! it took me to change the KEYA Value to 0xD3, 0xF7, 0xD3, 0xF7, 0xD3, 0xF7 and it worked, i just tryed a series of Common Key A Values! Many Many Thanks!
