The technology was developed by Kovio Inc. (San Jose, Calif.), a company that Thin Film (Oslo, Norway) acquired earlier this year.

Thin Film now calls the technology OpenSense and has signed up drinks company Diageo plc to use the technology in a “smart bottle” that will be prototyped with Johnnie Walker scotch whisky.

The OpenSense technology is said to enhance product security in such areas as wine and spirits, pharmaceuticals, cosmetics, health and beauty care, and automotive.

The printed tag is readable from an NFC-capable mobile phone before and after the factory seal has been broken. A unique identifier within each OpenSense tag supports a range of marketing, authenticity and security applications. The tags can be operated with a cloud database so that each bottle can be tracked for supply chain analytics. Dynamic mobile content can be sent to consumers depending on whether the bottle is closed or open.

Thin Film claims the printed nature of its OpenSense tags makes them superior to more traditional radio-frequency identification (RFID) solutions. Principally they can be lower cost and scale to high volume.

“We believe Thinfilm’s OpenSense technology is game-changing and will deliver tremendous benefits across a range of markets and industries,” said Davor Sutija, Thinfilm’s chief executive officer, in a statement.

The key specifications are:

13.56MHz operation for compatibility with fixed and mobile NFC readers, from smartphones to industrial readers.

128-bit ROM (roadmap to 256 bits).

Adheres to subset of ISO14443 Type-A RFID standard.

106 Kbit/sec data transfer, Manchester bit encoding and OOK load modulation at 847kHz.

16-bit CRC for data integrity verification.

Can be combined with tamper-evident adhesives and labels to increase security for packaging applications.
