Question

I am currently have the problem with writing into NFC Mifare Ultralight C tag from NXP. For the Arduino with given libraries from SeeedStudio or Adafruit. They only give supported examples with Mifare classic standard with blocks/sectors, and does not support Mifare Ultralight C with pages. Do anyone can give me the hint to work with this kind of tag? I want to write the key to the tag for authentication purpose.

Was it helpful?

Solution

I would suggest to follow one of these ways:

  1. You can dig into the datasheet(s) of the Ultralight tags and the NFC controller (PN532?). If you have time - that is a good way to understand the stuff.

  2. Another option is to get the code examples from the project.
