ReadNFC function

Posted on by Seahawk55

I have been developing a canvas app on PowerApps that reads information from two screens, each using readNFC to read the info, then compares the two results and accesses a collection and returns a result.

All has been working perfectly until late last week (4 Oct). I made a small adjustment to a timer saved and published,, The app did not open the NFC reader on the first screen (it was just blank) then went immediately to the second screen where again it wouldn't open the reader. Then it just stopped and waited.
I returned the timer value to it's original value and published. Didn't work. I tried different phones, Apple and Android, no good.

I closed the app and opened a previous version on my IPhone, it worked perfectly. I then opened the previous version in PowerApps and published it. After that the previous version failed.

All of my versions, saved during development, work before re-publishing and fail afterwards.

I'm sorry for the long winded post but I am at a loss as to what is happening?

Hi Col

I think i have the same issue.

I have an older app using ReadNFC() and it is not working now. NFC iphone pop up is not showing and a Tag can´t be recognized.
I created a new app and only put a button with ReadNFC() on the onselect property. Then publishing but NFC iphone pop up is not showing.

Have the same issues as well. Older versions of the app work with no issues but if I make any changes at all the NFC reader stops working

I got same issue, 02.10.2024 last published app. ReadNFC works fine. Next publish 08.10.2024 and ReadNFC is not working. Looks like some released update bricked NFC functionality. For me when i restore app published 02.10 ReadNFC works, with updated or new app ReadNFC is not working.

Same issue here.
A small thing that you can change to make it work again is to select an older version of power apps.
Inside your canvas app you can go to settings => support => Authoring version (Edit) and select an older version until this issue has been resolved.

Ok so Microsoft know about the issue and working to fix it.
I reverted back to an older version of Power Apps and then it works fine.
