Thanks for getting back to us with that information. That’s an interesting discovery and shows that some of these RFID tags may be defective, although it seems unusual for two of them to fail.
Are the app and RFID stickers working correctly now?
I’m also curious whether anyone else has experienced this issue.
Yes, the rest of the RFID tags i have used are working just fine. I managed to write 6 spool with out issue. When The second tag failed i was like there is no way it the tags.
