I started out years and years ago with the E2550 then got the Galaxy ACE then the S4 Mini, then the S5 Then the A6+ Then the A30 Then the A21S Then the A31S Then the A12 and then currently the S21 FE as well as multiple other devices and accessories ...
My A21 S does not have NFC but my Galaxy watch active does and I use Samsung Pay with the watch instead but the watch seems to struggle a lot with some card Machines
With FNB you need their mobile app it makes it way easier to link your card to Samsung Pay with that. then there isn't any complications with going to the bank and struggling with them.
