[HELP] programming from scratch for nfc tags

[Rachel RC]

Hi guys,

I'm doing a project for my final year that involves programming NFC tags. I am confused as to which software to use to program the tags from scratch. How do I start? All the posts I have read, only says to program using mobile applications. I also don't understand how to use libnfc and from what I understand, Open NFC is just to simulate an NFC-enabled device, which i dont need as I already have a real NFC device. I really need help urgently, could someone please clarify my confusion? Thank you for your time.

Hi Rachel,

To format tags so that they are recognized as nfc tags you can use:
* as mobile application: NXP Tagwriter
* with a PC:
** for NFC Tag Type 4 / DESFire:
from libfreefare look at mifare-desfire-format,
mifare-desfire-create-ndef, mifare-desfire-write-ndef,
mifare-desfire-read-ndef
** for Mifare Classic (not officially a NFC tag but works with some mobiles)
from libfreefare look at mifare-classic-format,
mifare-classic-write-ndef, mifare-classic-read-ndef
** for NFC Tag Type 2: no need to format, just read the NFC Tag Type 2
spec and write the proper content with nfc-mfultralight from libnfc

I hope it helps.
