Smartrac introduces Circus Tamper Loop Pro

The new product extends the tamper detection and authentication features of the Circus Tamper Loop tags with advanced cryptographic capabilities provided by its Pro level IC. Typical application areas comprise the authentication of pharmaceutical products and luxury goods from premium liquors to high-quality watches.

The product’s tamper-loop design enables an 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. Moreover, the tamper loop status is irreversibly stored in the IC memory and can be checked at the tap of a smartphone via a programmed on-chip URL. Secure authentication can be set to start creating one-time password values either before or after the loop has been tampered.

The Circus Tamper Loop Pro comes with 144 Byte user memory with password protection, works with all NFC reading devices, and is compliant to both NFC Forum Type 2 specifications and the ISO 14 443 A standard.

‘By combining a digital seal functionality and advanced cryptographic capabilities, the new Circus Tamper Loop Pro inlays and tags meet the requirements of many customers looking for highly secure product authentication and brand protection, consumer engagement, customer loyalty programs or protected content distribution’, said Dr Juha Virtanen, head of R&D, at Avery Dennison Intelligent Labels.
