RFID UHF chips, generally, are based on ISO18000-6C standard (There are chips that work with ISO18000-6B, but we don’t consider them).
UHF frequencies guarantees reading distances up to 10meters and chips, generally, have a EPC memory (modifiable tag code), a TID memory (transponder Identifier) and different size user memory .
We propose below some chips:
Alien Higgs3: Chip of interesting features, both for user memory size (512bit) and for high performance as reading distance. Watch Product page for further information.
Alien Higgs4: Chip very intersting becuase of the cost, very low, and the performances, seriously improved, compared to Alien Higgs3. User memory is reduced to 128bit. Watch the Product page for further information.
NXP UCODE7: Without user memory and with 128bit EPC memory is a very simple and low-cost chip. watch Technical datasheet for further information.
NXP UCODE DNA: Chip based on GS1 Gen2 V2 standard with encryption, it is untraceable with a 3072bit user memory. Watch Technical datasheet for further information.
