Targeting a wide array of applications for packaged goods in consumer and industrial markets, Circus Tamper Loop opens the door to new, NFC-based consumer experience solutions featuring higher security and additional consumer engagement at the point of sale and post-sale.
Circus Tamper Loop tags are based on the Smartrac Circus product family. While retaining Circus’ basic small form factors, the new tags come with a tamper-loop extension to the established antenna design. This loop enables advanced “digital seal” functionality for smart packaging and brand protection.
The design of the loop can be customized to suit individual customer requirements, and can be adapted to fit a wide variety of packaging formats — from boxes to blister packs to bottles.
The loop exhibits one of two visible conditions: a closed loop shows that the packaging is sealed, while an open loop indicates an open package. When the customer opens the sealed package, the loop is physically broken. The tamper detection status can be checked at the tap of a smartphone via a programmed on-chip URL or via an app. This offers higher security and improved counterfeiting protection.
Circus Tamper Loop is available with NXP’s NTAG 213 TT chip. The chip features 144 bytes of user memory, and comes with a unique ID (UID) mirror functionality. This enables the chip serial number to be ´mirrored´ as part of its encoded URL address, which makes each single chip uniquely identifiable when a smartphone taps the tag and is forwarded to the encoded URL link.
“Our new Circus Tamper Loop tags enable tamper detection and authentication at the tap of a smartphone for a wide range of products – whether it’s highly effective pharmaceuticals, top-grade cosmetics, high-performance brake pads, vintage wines or Beluga caviar,” said Dirk Boltersdorf, head of product management Inlays & Tags at Smartrac.
