End-user benefit

  • Retailers differentiate themselves from competition as they become trusted retailers that only sell authentic products.
  • Brands are provided with a strong method to prevent that low quality fake products get sold under their name and damage the brand. Brand value increases as trust of the customers goes up.
  • Consumers know that they get value for money. Not having to worry if the product at hand holds what the brand name promises.

Antenna design benefits

  • High sensitivity enables smaller and cost efficient antenna designs
  • Selected chip impedance enables reuse of antenna designs from UCODE 7xm or UCODE DNA

Label / module manufacturer benefit

  • Large RF pad-to-pad distance to ease antenna design
  • Symmetric RF inputs are less sensitive to process variation
  • Single-slit antenna for a more mechanically stable antenna connection
  • Pre-serialization of the 96-bit EPC
  • Extremely fast encoding of the EPC content

Supported features

  • All mandatory commands of GS1 UHF RFID Gen2 v2.0 are implemented
  • The following optional commands are implemented in conformance with GS1 UHF RFID Gen2 v2.0 specification:
    • Access
    • Authenticate
    • BlockPermalock (block size = 265 bits)
    • BlockWrite (max. 32bit, even address only)
    • ReadBuffer
    • Untraceable
  • Product Status Flag bit: enables the UHF RFID tag to be used as EAS (Electronic Article Surveillance) tag without the need for a back-end database.
  • Tag Power Indicator: enables the reader to select only ICs/tags that have enough power to be written to.
  • Parallel encoding: allows for the ability to bring (multiple) tag(s) quickly to the OPEN state and hence allowing single tags to be identified simply, without timing restrictions, or multiple tags to be e.g. written to at the same time, considerably reducing the encoding process

Part numbers include: SL3S5050N0FUD.
