Engineering Brief

The NTAG 22x StatusDetect family consists of NFC Forum Type 2 compliant tags operating at 13.56 MHz with ISO/IEC 14443-A interface. The distinguishing feature is an integrated tamper detection loop that monitors the physical integrity of seals or labels; when the loop is broken, the status is stored in memory and can be read wirelessly. This enables applications requiring both NFC data communication and tamper-evident functionality, with variants offering 144 or 168 bytes of user memory, password protection, and originality signatures for authentication.

Frequently Asked Questions

What is NTAG 22x StatusDetect used for?

NTAG 22x StatusDetect is designed for tamper-evident seals and labels that require both NFC communication and physical integrity monitoring. When the integrated detection loop is broken, the tamper status is permanently stored and can be read wirelessly.

How does NTAG StatusDetect tamper detection work?

The chip features an integrated tamper detection loop that monitors the physical integrity of seals or labels. When the loop is broken (e.g., if a seal is removed or damaged), the chip stores this tamper event in memory, allowing readers to verify whether the seal has been compromised.

What is the memory size of NTAG 223 vs NTAG 224?

NTAG 223 offers 144 bytes of user memory, while NTAG 224 provides 168 bytes of user memory. Both variants include password protection and originality signature features.

Is NTAG 22x StatusDetect compatible with standard NFC phones?

Yes, NTAG 22x StatusDetect is NFC Forum Type 2 compliant and operates at 13.56 MHz using ISO/IEC 14443-A protocol, making it readable by standard NFC-enabled smartphones and readers.

What security features does NTAG StatusDetect have?

NTAG 22x StatusDetect includes 32-bit password protection for access control, originality signature for authentication, and the tamper status detection loop for physical integrity monitoring of seals and labels.

Can NTAG StatusDetect detect partial tamper attempts?

Yes, when the integrated detection loop is interrupted or broken—even partially—the chip registers and stores the tamper event, which can then be detected during subsequent NFC reads to verify seal integrity.
