Control RFID card with MIT app inventor

Hi guys,

I want to use MIT app inventor as a place to store and control the information from RFID card (magnetic stripe card). For example, when the card is swiped, your temperature and heart rate will be saved to the card and they will show up on MIT app. Can you suggest a way to do so?

I appreciate any of your help. Thank you very much.

As far as I know NFC is rooted in radio-frequency identification technology (known as RFID ) which allows compatible hardware to both supply power to and communicate with an otherwise unpowered and passive electronic tag using radio waves.

Using near field components provided by app inventor will be a batter options

Here is a community discussion about RFID cards, NFC read/ write tags between phones not working (.aia file attached) . It may help you along with NearField and an old tutorial https://appinventor-mit-edu.ezproxy.canberra.edu.au/explore/ai2/cup-game

Or You can use RFID Mifare tag with this extension,

writing abd reading the data as explained in the demo project
