NFC Digital Keypad

The purpose of this app is to communicate with electronic projects, like Arduinos, through NFC tags. This app can read and write to NDEF NFC tags.
When an Arduino or other electronic project is connected to a PN532 NFC Reader, they can read the NFC tag and react accordingly. This app can change the message on an NFC tag, so the NFC reader reads whatever was sent to the NFC tag.
This app includes a keypad to send quick data, a console to debug and send long strings, and an instructions page with helpful links.
NFC is an alternative to Bluetooth and WiFi, and this app would be best when the project requires a very quick connection time and a very short range.
