End user benefit

  • Tag authentication based on cryptographic security
  • Privacy protection based on cryptographic security
  • Long read/write ranges due to leading edge chip sensitivity
  • Hassle-free deployment even without significant security knowhow and even without secure backend infrastructure due to NXP’s Trust Provisioning service offering
  • Reliable operation in dense reader and noisy environments through high interference rejection

Antenna design benefits

  • High sensitivity enables smaller and cost efficient antenna designs
  • Selected chip impedance enables re-use of antenna designs from UCODE 7

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
  • Automatic self pre-serialization of the 96-bit EPC
  • Extremely fast encoding of the EPC content
