With NFC Reader you can read tags, save them for later viewing, share them, save contacts, open URLs and more! Be advised: Reading NFC tags requires iPhone 7, 8, or X. FAQ: - Will my iPhone work with NFC? That depends: iPhone 7 and up supports NFC reading and NFC reading only works when NFC tags are NDEF formatted. If you're not sure what that means, you can reach out to our support for more information. - Are NFC tags RFID tags? No, NFC NDEF tags are not RFID tags - this means your gym cards, debit/credit cards, hotel cards, etc aren't readable by this app. - Will this app help me pair to my speaker/router/camera/etc? No, this app doesn't support deep integrations into NFC enabled products - this app is intended to read NFC tags and display data within those tags. Some tags contain actionable data like website URLs, text messages, geotags, contact cards, etc. If you have any questions, reach out to me at andrew@baristable.com
