The test sample is placed on a thin sheet of plastic connected to the movable part of

the fixture. Then the distance is carefully adjusted until the reader can no longer read

the sample, thus the maximum interrogation distance is displayed in the ruler.

3.2. RFID tags used for test

A total of 10 RFID tags were used to measure the interrogation distances. The next

picture shows type 1, type 2 and type 4 tags, respectively.

Type 1 tag is based on ISO/IEC 14443A standard and has 512 bytes of memory.

Type 2 tag is based on ISO/IEC 14443A standard and has 192 bytes of memory.

Type 4 is based on ISO / IEC 14443A 1-4 compliant and has 2K of memory.

The next picture shows the Tag-it HF-I RFID tags from Texas Instruments: RI-102-

112, RI-I11-112, RI-I03-112, RI-I16-112, Button and RI-I17-112.
