  • Tag Read. RFID tags have a unique serial number that can be read by the Tru-Test EMM and thus linked integrally to a cow and a sample. Laboratory readers are available that can read the information from vials in seconds.
  • Tag Write. The Tru-Test EMM can write information to the tag such as the animal ID, milk yield and milking time. This can be used in the laboratory as a back-up to the data stored in the Data Handler, or the tag can be used as the main data carrier.
  • Tag retention. The RFID vial tag is retained underneath the vial. It is not in contact with the milk. The vial can accomodate a variety of commonly available tag sizes. Should the vial become damaged, the RFID tag can be
  • Read/Write Range. The read range for tags can vary and should be thoroughly tested with the Tru-Test EMM before committing to a type. Tru-Test can recommend tag brands.
  • Memory. Memory size typically ranges from 256 bit to 10 kbit. 2 kbits is recommended if information is to be written to the tag. There is of course a price vs memory size trade-off.
  • Ruggedness. Not all tags are made to withstand frequent washing and temperature changes. Tru-Test recommends laundry tags for this reason.
  • Format. Tags come with a variety of data formats. The Tru-Test EMM may need to be configured for a particular format.
