Start with the basic test#
Unlock the phone, wake the screen and slowly move the back of the device across the marked NFC area. Antenna position differs between models.
iPhone and Android checks#
On recent iPhones, try the top edge or upper back for one or two seconds. Remove thick or metallic cases. On Android, search Settings for NFC and confirm it is enabled; Google notes that the exact path varies by device. The antenna is commonly near the centre or upper back.
Metal tables, magnetic holders, wallet cases and several tags placed together can reduce readability. Test the tag away from the installation surface and without the case.
Tag or link?#
If a notification appears but the page fails, NFC probably worked. Check connectivity and open the same URL manually or through the backup QR code. If several phones cannot read the tag in neutral conditions, contact support with the phone models and installation details.
Good to know
Should the phone be unlocked?
Where is the NFC antenna?
Can a metal table interfere?

An NFC stand opens the right link with one phone tap. No app and no searching.
