What is RFID Card Protocol?
RFID Card protocol defines rules and standards for communication between RFID cards and readers, covering common ISO10536, ISO14443, ISO15693 and ISO18000.
Want to attach NFC cards to mobile phones, posters, or small toys, but don’t know what capacity to choose? The following article will help you understand the differences between NTAG213, NTAG215, and NTAG216 NFC cards in 3 minutes, and easily choose the right capacity.
(Keywords: NTAG216 NFC Cards)
| Chip | Available Capacity* | Suggested Use | Cost Estimate |
|---|---|---|---|
| NTAG213 | 144 bytes | Single task command, URL jump, Bluetooth pairing | Low |
| NTAG215 | 504 bytes | Multi-task automation, Wi-Fi sharing, e-tickets | Medium |
| NTAG216 NFC Cards | 888 bytes | NFC business cards, simple data storage | Slightly higher |
* Available capacity is the actual writable space after deducting system data.
Single command ≈ 45 bytes
For example: turning Wi-Fi or Bluetooth on/off, adjusting brightness, pausing the media player, etc.
→ NTAG213 is enough.
NFC business card ≈ 159 bytes
You can include your name, phone number, email, company, and website.
→ Start with NTAG216 NFC Cards so you won’t run out of space.
vCard with pictures / small files
These require large-capacity NFC cards of 4000 bytes or even 8000 bytes, which are beyond the scope of this article.
| Fungere | NTAG213 / 215 / 216 Common Features |
|---|---|
| Operating frequency | 13.56 MHz |
| Transmission rate | 106 kbit/s |
| Læs afstand | About 5–10 cm (depends on antenna and device) |
| Data retention | 10 years |
| Write life | 100.000 gange |
| Sikkerhed | 32-bit password, ECC digital signature, lockable pages |
Material tip:
If you want to make electronic business cards eller access control cards, choose PVC eller KÆLEDYR. For keychains or waterproof cards, go for ABS housing or surface coating for better durability.
Only need single command use → 144 bytes is enough.
Want automation + business card → Get NTAG216 NFC Cards to avoid upgrading later.
DIY users → Choose 504 bytes or more for greater flexibility—the price difference is minor.
If you want small capacity and low price, choose NTAG213.
If you want advanced features and NFC business cards, choose NTAG216 NFC Cards.
Capacity defines your possibilities—don’t wait until it’s full to regret your choice!
