ACG HF Multi ISO RFID Reader V1.0
ACG Identification Technologies GmbH 27
7 ISO 15693
The reader can communicate with ISO15693 tags. An anti-collision is needed if
multiple instances of tags are in the same antenna field. The reader detects each
type of ISO15693 labels and handles them individually
7.1 Coding of UID
The UID of a tag is defined in ISO/IEC 15693-3. All tags compliant to ISO15693
support the specified format. The UID is factory programmed and cannot be
changed. The UID is needed for the anti-collision sequence to separate several tags
in the same antenna field.
