Our Circus™ Tamper Loop tags have been specifically designed for tamper detection and authentication, targeting a wide array of applications in packaged goods for consumer and industrial markets. The tag opens the door to entirely new, NFC-based consumer experience solutions featuring higher security and additional consumer engagement at the point of sale and post-sale. 

Circus™ Tamper Loop is based on the well-established Circus™ product family and comes with a tamper-loop design. This loop enables advanced digital seal functionality for smart packaging and brand protection. It exhibits one of two conditions: a closed loop shows that the packaging is sealed; while an open loop indicates an open package. The tamper detection status can be checked at the tap of a smartphone via a programmed on-chip URL. 

Moreover, products can be authenticated at any stage in the supply chain by verifying their digital identity. Even in the case of an open loop, the Circus™ Tamper Loop can be read with a smartphone to display a consumer experience specific to an opened package. At any time, it can be exploited for further pre- and post-sales activities. 

The small Circus™ Tamper Loop is available with NXP’s NTAG 213 TT chip that provides additional features compared to the NTAG 213. It offers tamper detection with once-opened status and NXP original signature with an option of a brand-unique signature.
