MMEETT has programmed over 50,000 NFC business cards. The average first-time user completes programming in under 4 minutes with NFC Tools.
The best no-cost option is NFC Tools by wakdev, available on both iOS and Android. It supports every common tag type and is updated regularly. For MMEETT cards, the MMEETT companion app adds cloud profile syncing and analytics.
Open the app and select "Write." Choose from these data types:
For a business card, enter the URL of your digital profile or landing page. Example: https://aicard.autorunbiz.com/yourname. Keep the URL short — tag memory is limited (144–888 bytes depending on the chip).
Place the NFC card flat against the phone's NFC zone:
Hold steady until the app confirms "Write successful." This usually takes 1–2 seconds.
Do not assume it worked. Tap the card to a different phone — ideally one running a different OS — to confirm the data reads correctly and the link opens. If it fails, erase and rewrite.
NFC Tools offers a "Lock" option after writing. Once locked, the tag cannot be rewritten without special equipment. Lock if the data is final. For MMEETT C04, cloud-linked profiles update remotely without re-writing the physical tag — no locking needed.
| Tag Chip | Memory | Best For |
|---|---|---|
| NTAG213 | 144 bytes | Short URL only |
| NTAG215 | 504 bytes | URL + small vCard |
| NTAG216 | 888 bytes | Full vCard or long URL |
NFC Tools (no-cost app, iOS/Android) is the most reliable app. Manufacturer apps like MMEETT's companion app also work and add cloud-sync features.
Yes. iPhone 7 and newer with iOS 13+ can write NFC tags using NFC Tools or the Shortcuts app. The phone must touch the tag at the top-center edge.
A URL linking to your digital profile is most reliable. vCard format works but can be too large for basic tags. Plain text is the simplest fallback.
Lock the tag if the data is permanent. Leave it unlocked if you plan to update your profile URL regularly. MMEETT C04 uses cloud-linked cards that update without re-writing.
NTAG213/215/216 tags can be rewritten 100,000+ times. The memory limit is the constraint — 144 bytes for NTAG213, 504 bytes for NTAG215, 888 bytes for NTAG216.
