ISO/IEC 18000-6C Certification

ISO 18000 Series standard ( ISO 18000-6C) Certification 

ISO/IEC 18000 describes a passive backscatter RFID system that supports the following system capabilities:

• Identification and communication with multiple tags in the field

• Selection of a subgroup of tags for identification or with which to communicate

• Reading from and writing to or rewriting data many times to individual tags

• User-controlled permanently lockable memory

• Data integrity protection • Interrogator-to-tag communications link with error detection

• Tag-to-interrogator communications link with error detection.

• Support for both passive back-scatter tags with or without batteries.

In this RFID system, the interrogator powers and communicates with the tags that are within range. Tags receive data as amplitude modulation of the power/data signal from the interrogator. During the time that the tag responds to the interrogator, the interrogator transmits at a constant radio frequency power level, while the tag modulates the impedance of its radio frequency load attached to the tag antenna terminals. The interrogator then receives the data back from the tag as a variation in a reflection of its transmitted power.
