Read and write vaccine records on NFC tag
This CRUD Arduino program stores vaccination information on NFC chips using the Adafruit PN532 NFC/RFID Controller Shield. I built this for Khushi Baby in our first few weeks of prototyping. Because we were designing a mHealth system for resource-poor settings, we considered using a feature phone with a NFC reader instead of a smartphone. We eventually went with the smartphone, but not before I learned some Arduino!
