Chip integrates NFC & EPC Gen2V2 dual-frequency RFID
EM Microelectronic announced the EM4423 RFID circuit featuring a UHF EPC Gen2V2 RF and an NFC Type 2 interface. EM Microelectronic says device such as this is world's first and is uniquely 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.
EM4423 features common rewritable memory areas to simplify adoption of EPC inventory control procedures by smaller retailers who are not willing or able to make the substantial investment required for specialized RFID equipment and software. EM suggest similar functionality can be achieved through the use of mobile devices, such as smartphones and tablets and applications.
Other list of features of EM4423 as explained by EM includes:
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
“With its unique feature set, combining traditional EPC Gen2 logistics capabilities with the customer-focused benefits of NFC, the EM4423 is creating quite a bit of excitement with our RFID customers,” commented Michel Willemin, CEO of EM Microelectronic. “By enabling a low-cost, unified solution for logistics and marketing, EM brings value to and simplifies the lives of both small retailers and product manufacturers looking to differentiate their products.”
