- RFID/NFC Functionality: Read UUID, NDEF messges and potentially write data using the PN532 module.
- SD Card Operations: Seamlessly read, load, and delete files on the SD card.
- User Interface: Navigate options with three buttons connected to the OLED screen.
- Improve menu flow and button handling*
- Save scans to SD card : After reading RFID/NFC, save data to SD Card
- Write from SD card : Enter write menu, select SD Card, & choose which data to write.
More updates will be added soon!
