How to setup NFC on iphone 13 promax

NFC should already be turned on. Some iPhone 13 pro have scan distance issues which can affect the read ability of the NFC tag when scanning outside an app. However when scanned though an app, the phone should scan with no problems.

If you are still having problems scanning, iPhones aren't able to read tags that do not have encoding. They are also unable to read tags that have been encoded with a description in the URL or encoding with text. Check that the tag has already been encoded with a URL (without a description).
