Key benefits

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

Antenna design benefits

  • High sensitivity enables small and cost efficient antenna designs
  • Low Q-Value eases broad band antenna design for global usage

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

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.
