em | echo-T- NFC & High Frequency ICs, EPC and UHF ICs

Tamper-evident dual frequency RAINFC transponder IC

General Description

em|echo-T is part of the latest generation of EM Microelectronic Radio-Frequency IDentification (RFID) devices, combining Near-Field Communication (NFC) and RAIN RFID functionalities on a single die. Target applications and market segments include retail, product authenticity.

em|echo-T provides multiple benefits and usages via the RAIN RFID communication interface like supply chain management, stock inventory, product returns and data privacy. In parallel it enables customer engagement through product information and loyalty programs using an NFC-enabled smartphone. An electrical continuity loop check (“tamper detection”) provides a means to detect tampering with product packaging through both the RAIN RFID reader infrastructure for in-store inventory surveillance and end customer smartphones for product authenticity applications.

em|echo-T is a dual frequency device supporting ISO/IEC 14443A and NFC ForumTM Type 2 specifications on one side and RAIN RFID protocols ISO/IEC 18000-63 and EPCTM Gen-2v2, including extended privacy features, on the other. Each IC is manufactured with a 96-bit unalterable unique identifier (UID) used by both RF protocols. em|echo-T’s non-volatile memory is accessible from either RF air interface and supports BlockWrite commands, enabling fast encoding, as well as the Untraceable command to hide portions of memory of the tag or label to guarantee end-user privacy.

Tamper status can be optionally stored in non-volatile memory, enabling product packaging lifecycle management. Tamper evidence read-out using a smartphone is supported using a dynamic NDEF message implementation supported by both AndroidTM and iOSTM.
