Fully integrated NFC & EPC Gen2V2 dual-frequency RFID
The EM4423 is suited for manufacturers/brands which are compelled to support EPC functionality for retail logistics and inventory control, but who also want to communicate directly with the consumer for marketing and advertising, product authenticity, and product registration on a per-item level.
With common rewritable memory areas, a common Unique Identifier (UID) and value-added privacy and security features, the EM4423 also simplifies adoption of EPC inventory control procedures by smaller retailers who are not willing or able to make the substantial investment required for specialised RFID equipment and software. Similar functionality can be achieved through the use of mobile devices, such as smartphones and tablets and applications.
As a single chip NFC/EPC solution with common memory, the new device offers;
One-step NFC/EPC inlay manufacturing
Dual-interface memory access (NFC and/or EPC)
EPC for fast data collection & long range
NFC access to consumer data and secured access (e.g. digital signature for tag and product authenticity)
NFC field powering option for increased UHF performance and reading range
NFC access counter readable through EPC air interface
Enhanced privacy features including EPC Gen2V2 “UNTRACEABLE” command
Large user data – more than 2kbit
