Engineering Brief

The UCODE G2iM/G2iM+ family comprises high-sensitivity (-17.5 dBm) Gen2 UHF RFID chips optimized for retail, fashion, and authentication. The G2iM offers 256-bit EPC and 512-bit user memory, while the G2iM+ extends this with segmentable user memory (up to three access-level zones), 128–448 bit EPC, external supply mode (boosting sensitivity to -27 dBm), tag tamper alarm, digital I/O, and conditional read-range reduction for privacy. Both variants include Product Status Flag (PSF) for EAS, bank-wise read protection, 48-bit unique serial number, and support standard EPC commands plus custom ChangeConfig/EAS_Alarm commands for streamlined deployment.

Typical Applications

  • Fashion apparel and footwear item-level tagging
  • Retail supply chain and inventory management
  • Product authentication and brand protection
  • Electronic article surveillance (EAS) with integrated PSF flag
  • PCB tagging and electronics activation/configuration
  • Asset management and container tracking
