Product details

Overview

ST25-TAG-BAG-UB from STMicroelectronics is a ready-to-use evaluation kit containing 17 physical NFC tags based on ST25TV02K, ST25TV02KC, ST25TA02KB, and ST25TA64K ICs - compliant with NFC Forum Type 4 (ISO/IEC 14443-A) and Type 5 (ISO/IEC 15693) standards. It includes tamper-detect stickers, on-metal PET tags, LED-integrated PVC cards, and FPC cards - enabling rapid prototyping for asset tracking, smart packaging, and industrial authentication.

For engineers reviewing the ST25-TAG-BAG-UB datasheet, ST25-TAG-BAG-UB application, ST25-TAG-BAG-UB contents, or ST25-TAG-BAG-UB compatibility with ST25TA/ST25TV series ICs, this kit provides verified antenna-matched tag variants across memory sizes (512 bits to 64 Kbits), operating frequencies (13.56 MHz), and mechanical form factors (PET, PVC, paper, FPC) - supporting both short-range and extended-range NFC use cases.

Technical Context

The kit integrates four distinct ST25 NFC tag IC families: ST25TV02K (Type 5, ISO/IEC 15693, 2-Kbit EEPROM, tamper detection), ST25TV02KC (Type 5, same core with enhanced coil coupling), ST25TA02KB (Type 4, ISO/IEC 14443-A, 2-Kbit EEPROM, fast read/write), and ST25TA64K (Type 4, 64-Kbit EEPROM, support for NDEF formatting and dynamic locking).

Each tag variant pairs its IC with purpose-built antennas: on-metal PET enables operation on conductive surfaces; LED-integrated PVC card provides visual feedback upon field activation; FPC cards embed flexible printed circuits for curved or space-constrained mounting; tamper-detect stickers break electrical continuity upon removal - all validated per NFC Forum compliance test plans.

FAQ

Is ST25-TAG-BAG-UB compatible with Android and iOS NFC readers?

Yes - all included tags comply with NFC Forum specifications and operate at 13.56 MHz. ST25TA-series (Type 4) tags are natively supported by Android's default NFC stack and iOS 13+ Core NFC framework for reading NDEF messages. ST25TV-series (Type 5) tags require reader-side ISO/IEC 15693 support, available on many industrial scanners and Android devices with custom HAL extensions.

What is the difference between ST25TV02K and ST25TV02KC in this kit?

The ST25TV02KC is an enhanced version of the ST25TV02K with improved antenna coupling efficiency and tighter tolerance on resonance frequency (13.56 MHz ±7 kHz vs. ±15 kHz). It delivers more consistent read range on small or lossy substrates and is specifically tuned for the included PET sticker form factor.

Can the tamper-detect tags be reused after removal?

No - the tamper-detect function relies on a physically broken conductive path within the antenna loop. Once peeled from the surface, the circuit opens permanently, triggering a status flag in the IC's tamper register. This irreversible change prevents reuse and confirms unauthorized access in security-critical deployments.

Does the LED-integrated PVC card require external power?

No - the LED is powered solely by the RF field during NFC interrogation. It lights only when an active reader is within ~3 cm and transmitting sufficient field strength (≥1.5 A/m). No battery, wiring, or PCB traces are needed - the LED is directly coupled to the antenna via integrated rectifier and current-limiting circuitry.
