Thanks to everyone's support this week, Smart NFC hit #1 in Dev Tools on the US App Store! It's been a great first year with you all, and I can't wait to release 2.0!

NFC is supported on iPhone 7 or newer only; iPad and iPod Touch do not have the hardware to interact with NFC tags.


Read, write, interact, and hack your NFC tags on your supporting iPhone!

Smart NFC is one of the first apps to support native NFC writing directly from your device. With numerous custom records to get you started, you'll be writing to most NDEF-formatted NFC tags in no time. Don't have any NDEF-formatted tags? Format them in the Advanced section.

Tag-specific features are being added that allow you to edit a tag's memory directly, which opens the doors to all kinds of new features!

Tag not scanning? NDEF format new tags from the Advanced section to get them working right!

An NFC tag is written with a single "Message" which contains any number of "Records." These records define text, links, and data to be stored on the tag. Most tags can be scanned by holding the top of your iPhone within a few centimeters. A chip is only limited only by its size. As long as the chip is NDEF-formatted (most are, and other formats will be supported in a later version) and it has enough space, the limits are endless!

- Read, write, duplicate, erase, and permanently lock NDEF-formatted tags
- Monitor a tag's max capacity (usually somewhere between 256-1024 Bytes)
- Read, write, and interact with links (https://, sms://, facetime://, mailto:, etc.)
- Write a variety of pre-defined Social Media and website records
- Read and write text records with multiple language localizations
- Use Background Tag Reading to interact with NFC tags without an app. Write a link to a tag and then tap it to your phone. Voila! (Supported on iPhone XS and newer)
- Review and rewrite previous messages from your History to another tag
- Format factory-programmed tags as NDEF tags in-app (Supports most common tags such as Type 2 and Type 5 NFC tags)
- Read and write directly to a tag's memory
- Send custom commands directly to a tag
- And of course, target your users better by using a tag's unique identifier

- Dark Mode
- Privacy: we collect nothing as you use the app.

Supported Devices:
- NFC scanning is available on iPhone 7 and newer. iPad and iPod Touch do not have the required hardware.
- Background Tag Reading is available on iPhone XS and newer. iOS will present a notification for the first valid link stored on a tag.

Supported Tags:
- Any NDEF-formatted tags
- MIFARE Ultralight
- NTAG 213/215/216
- NXP ICODE® Tags, ISO 15693 Tags, and Type 5 Tags

Future support for:

Future features:
- Include a tag's ID and/or its read count in a record
- Password-protect an NFC chip
- Connect to a Bluetooth device

Full Featured NFC App

This is the best NFC app that I could find for iPhone when tinkering with some pesky NFC tags. Unfortunately my tags were password protected, and the only advanced option for my tag type was to remove the password. Overall, still a great app.

Developer Response ,

I love hearing that people are enjoying my app! Passwords are tricky, and commands can be combines with the password validation command, but 99% of the time it's easier to remove and re-add the password. Otherwise you'll have to send all the commands manually, and trust me, that's not pretty 😅

It crashes when I try to change protocols

I’m having trouble writing to Type 5 tags because the app crashes when I use the advanced mode and change protocols.

Developer Response ,

I'd love to resolve this issue. Would you reach out to me on Twitter at @0xA1EC?
