2 Key benefits
2.1 End user benefit
- Prevention of unauthorized memory access through 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 extended TID range, including a 32-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
- Fast first WRITE 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 including CRC16 from unauthorized reading.
- ChangeConfig
- Configures the additional features of the chip like external supply mode, tamper alarm, digital switch, read range reduction or data transfer.
The UCODE G2iL is equipped with a number of additional features and custom commands. 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.
