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
