Yesterday I was playing around with my #NFC tag.
The tag written by the Android version of "NFC Tools" couldn't be read by the desktop version.
Also, some Python tooling for reading #NDEF messages couldn't parse the message - apparently it was invalid / malformed?
Still, I learned that these NTAGs are basically Mifare Ultralight tags - when it comes to libnfc tooling.

This new "Dynamic NFC Tag" board from #SparkFun looks pretty neat. Acts like a programmable NDEF NFC for use w/ iPhone & Android and has chainable Qwiic / StemmaQT I2C connectors https://www.sparkfun.com/products/21274

Not any new app I've written, but both #MiFare classic and #NTAG formats can carry an #NDEF payload; there are many different payloads two of which are WiFi connections and contact cards. NTAG is usually the better choice as it is almost universally readable whereas only certain Android phones can read MiFare tags.

Easiest way to do this is score some writable NTAG cards/chips and use NFC Tools (app) on your phone to write the payload. Read and emulate the tag you write on Flipper :)
