‘No supported app for this NFC tag’.
NFC is a popular technology that can be found in most high-end smartphones.
In addition to phone-to-phone communication, small NFC tags can be used to store and transport data.
So, why does my phone continually tell me that the NFC tag isn’t working, or is not supported?
The Android system (or more specifically, the NFC system service) displays the message “NFC tag type not supported” both before and after dispatching the tag to your app.
This means that the NFC system service filters MIFARE Classic tags and never
informs any apps.

How Does The NFC Tag Work
NFC tags are passive devices, which means they don’t have their own power
source and must wait for an active device to get into range before being activated.
The trade-off is that these gadgets can’t really do any processing on their own;

We won’t get too technical here, but the basic idea is that electromagnetic
waves can be generated by coils of wire, which can then be picked up and
converted back into electricity by another coil of wire.

How to Fix “This NFC Tag Doesn’t Support Any App” Pop-Up
Turning off the NFC and payment features is the simplest way to stop the unpleasant pop-up from appearing, but NFC is a commonly utilized feature for certain individuals, so we’ve included additional solutions as well.
A) Invest in an RFID-blocking wallet.
If you want to keep all of your cards but don’t want to see the pop-up again,
you can purchase an RFID wallet case that renders your cards
electromagnetically opaque, preventing the NFC reader from detecting them
until you remove them from the wallet.

(You don’t need to disable NFC, and this also protects against RFID skimming.)
B) Sandwich a piece of paper between the phone and the cards.
If you don’t want to buy a new wallet cover, you can use a sheet between the cards and the phone.
Using an aluminum sheet with a thickness of 1.2mm should fix the pop-up problem.
If you can’t find a sheet that thick, wrap your cards in a newspaper.
C) Disable NFC on your device.
You can easily remedy this by turning off NFC on your phone, but you’ll need to
turn it back on to make contactless payments with Samsung Pay or other comparable apps.

If that’s acceptable with you, go to the steps below:
Step 1: Locate and open “Settings” in the App Drawer.
Step 2: Click on “Connections” from the drop-down menu.
In most Samsung devices, the NFC option is found under “Connections,”
however, in other devices, it is found under Bluetooth & device connection.
If you can’t find it, go to “Settings” and type in “NFC.”
Step 3: Switch the NFC toggle switch off.
Turn off the NFC toggle switch if you see one, and the pop-up should disappear.
D) Sign up for Samsung Pay with your credit and debit cards.

Unregistered cards can also lead to this, as stated previously.
If you only have your bank cards, you can register them with Samsung Pay
to see if it solves the problem.
Note: If you keep public transportation or other cards with an NFC tag,
this will not function.
Payment programs like Samsung Pay can only accept debit and credit cards,
which is why the “No supported ” message appears.
Note that the notification panel also allows you to disable NFC and payment.
