Product details
Overview
ST25-TAG-BAG-U from STMicroelectronics is a pre-assembled evaluation kit containing five distinct NFC tag variants: five ST25TV02K paper labels, five ST25TA02KB PET labels, five ST25TV02K PET labels, five ST25TV512 paper labels, and five ST25TA64K paper tickets - all based on NFC Forum Type 4 (ST25TA series) or Type 5 (ST25TV series) ICs with memory sizes from 512 bits to 64 Kbits.
For engineers reviewing the ST25-TAG-BAG-U datasheet, ST25-TAG-BAG-U contents, ST25-TAG-BAG-U application scope, or ST25-TAG-BAG-U equivalent kits, this bundle supports rapid comparative testing of antenna form factors (paper vs. PET), memory capacity (512b–64Kb), and NFC protocol compliance (ISO/IEC 14443 A/B vs. ISO/IEC 15693) across industrial labeling, smart packaging, and asset tagging use cases.
Technical Context
The ST25-TAG-BAG-U integrates NFC Forum Type 4 Tag ICs (ST25TA02KB, ST25TA64K) compliant with ISO/IEC 14443-4 and Type 5 Tag ICs (ST25TV02K, ST25TV512) compliant with ISO/IEC 15693. Each variant uses a tuned antenna matched to its IC's operating frequency (13.56 MHz) and modulation scheme (ASK 10% or 100%).
Tag substrates vary by type: paper labels support low-cost disposable applications; PET labels provide enhanced durability and moisture resistance; paper tickets enable flexible ticketing integration. All tags are pre-programmed with default NDEF messages and factory-configured for read/write operation without initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Contents | Five ST25TV02K paper labels, five ST25TA02KB PET labels, five ST25TV02K PET labels, five ST25TV512 paper labels, five ST25TA64K paper tickets |
| NFC Standards | Type 4 (ISO/IEC 14443-4 A/B) and Type 5 (ISO/IEC 15693) compliant - enables interoperability with smartphones and industrial readers |
| Memory Range | 512 bits (ST25TV02K) to 64 Kbits (ST25TA64K) - supports minimal ID storage up to rich NDEF payloads like URLs, vCards, or firmware metadata |
| Antenna Substrate | Mixed paper and PET materials - paper enables cost-sensitive labeling; PET provides mechanical robustness for reusable assets |
| Operating Frequency | 13.56 MHz - ensures compatibility with global NFC infrastructure and mobile devices |
| Default Configuration | Pre-programmed with standard NDEF messages and factory-set RF parameters - eliminates setup overhead during initial evaluation |

FAQ
Is the ST25-TAG-BAG-U intended for production use or only evaluation?
No - the ST25-TAG-BAG-U is explicitly designed as an evaluation kit. It contains pre-assembled, individually packaged tags for functional comparison and antenna performance testing. ST does not specify it for volume production deployment due to non-standardized packaging, absence of reel/tape formatting, and lack of production-grade traceability documentation.
Do the tags in this bag require external power or battery?
No - all tags in the ST25-TAG-BAG-U are passive NFC devices. They derive operating power entirely from the RF field generated by an NFC reader or smartphone during communication, eliminating need for batteries or wiring. This enables maintenance-free, multi-year operation in static labeling applications.
Can the ST25TA and ST25TV tags be reprogrammed in the field?
Yes - all included ICs (ST25TA02KB, ST25TA64K, ST25TV02K, ST25TV512) support over-the-air NDEF message updates via standard NFC readers or Android/iOS devices using compatible apps. Memory is organized in configurable sectors with lockable pages to prevent accidental overwrite of critical data.
What distinguishes the ST25TV02K paper vs. PET label variants?
The ST25TV02K paper label uses cellulose-based substrate for low-cost, printable, and recyclable applications such as retail shelf tags. The ST25TV02K PET label uses polyester film for higher tensile strength, chemical resistance, and thermal stability - making it suitable for industrial equipment labels exposed to cleaning agents or elevated ambient temperatures.
