Fix your digital wallet by switching to this new Samsung Galaxy S21 5G NFC antenna. NFC is used for a bunch of different tasks where the mobile phone must interact with another device and exchange simple information. If NFC does not work when you stand at the checkout in a store, or automatic transfer of contact information does not start, the NFC antenna may be broken. Changing to a new antenna when the old one is broken is the best thing you can do.

What does the NFC antenna on your Galaxy S21 use? A couple of examples include Samsung Pay/Google Play and connecting directly to bluetooth powered speakers or headphones.
