Android Question NFC polling after read


New Member
Dear Support

I’m a beginner using B4A but following the great tutorials I was able to write a APP for NFC read/write (based on the NFC examples)

For the moment when I tap a tag I receive the data, and display it. Then I need to edit some and write it again to the tag. If I don’t “remove” the tag from the proximity.. Everything works ok..

What I’m trying to accomplish is to scan a tag and then after the user edit the content.. Enter a while loop .. Polling/checking if the tag is in the proximity /in range again.. And then write the content..

Any advice??

Thanks again for the great tool
