Abstract
Description
technical field
[0001] The invention mainly relates to identification tags, and in particular to a system and method for simultaneously detecting 8.2MHz EAS tags and 13.56MHz ISO15693 RFID tags. Background technique
[0002] The use of EAS (Electronic Article Surveillance System) tags and RFID (Radio Frequency Identification) tags for various reading, tracking and / or detection applications is rapidly expanding. A smooth connection between the functionality of existing EAS and RFID is a consistent theme identified by users interested in RFID in order to allow them to profit from RFID while maintaining their high performance in EAS technology and unproven RFID Cost-effectively protects the investment in the practicality of low-cost sales objects. However, conventional methods of processing the respective EAS or RFID signals returned from tags exhibit certain disadvantages or limitations when identifying the frequencies at which the tags are capable of receiving EAS and RFID. ...
