2 Key benefits
2.1 End user benefit
  • Outstanding User Memory size of 640 bit
  • Prevention of unauthorized memory access through different levels of read protection
  • Indication of tag tampering attempt by use of the tag tamper alarm feature
  • Electronic device configuration and / or activation by the use of the digital switch / data transfer mode
  • Theft deterrence supported by the PSF feature (PSF alarm or EPC code)
  • Small label sizes, long read ranges due to high chip sensitivity
  • Product identification through unalterable TID range, including a 48 bit serial number
  • Reliable operation in dense reader and noisy environments through high interference suppression
2.2 Antenna design benefits
  • High sensitivity enables small and cost efficient antenna designs
  • Low Q-Value eases broad band antenna design for global usage
2.3 Label manufacturer benefit
  • Consistent performance on different materials due to low Q-factor
  • Ease of assembly and high assembly yields through large chip input capacitance and Polyimide spacer
  • Fast first WRITE or BLOCKWRITE of the EPC memory for fast label initialization
3 Custom commands
  • PSF Alarm
    • Built-in PSF (Product Status Flag), enables the UHF RFID tag to be used as EAS tag (Electronic Article Surveillance) tag without the need for a back-end data base.
  • Read Protect
    • Protects all memory content from unauthorized reading.
  • ChangeConfig
    • Configures the additional features of the chip like external supply mode, tamper alarm, digital switch, read range reduction, privacy mode activation condition or data  transfer

The UCODE G2iM+ is equipped with a number of additional features. Nevertheless, the
chip is designed in a way standard EPCglobal READ/WRITE/ACCESS commands can be
used to operate the features. No custom commands are needed to take advantage of all
the features in case of unlocked EPC memory
