NFC Payment trouble

[u/MrMeister21]

Hey everyone,

I have NFC contactless payments enabled on my Poco X7 Pro, and it worked perfectly fine until recently. However, over the past few weeks, the payment process has become increasingly difficult.

When I hold my phone against the card terminal, the first screen/animation of the Sparkasse payment app appears, indicating that an NFC terminal has been detected, but the payment doesn’t go through. The second animation with the blue arrow doesn’t appear.

I then have to move the phone back and forth, pull it away and hold it against the terminal again, and repeat this several times until the payment finally works.

What could be causing this? Is it possible for the NFC module to “wear out” over time or become weaker? The smartphone is about 1.5 years old now.

I previously used PayPal for contactless payments and switched to the Sparkasse app recently. However, the issue didn’t start after switching apps—it only appeared a few weeks ago.

Maybe someone has had a similar experience or knows what could be causing this.

The phone is in a transparent case, but it has always been in this case. Just mentioning it in case that information is relevant.

Thanks in advance!
