Claim:
1. A device for sampling and locating asset information including a tag, and a locator disposed on a rack for placing asset, wherein, the tag includes an attaching terminal comprising an attaching element, a RFID responder and a magnetic element disposed in the attaching element, wherein, the RFID responder is configured to store sampled information of the asset, wherein the tag further includes a fixing end configured to fix the tag to the asset whose information would be sampled, and a flexible connection element connecting between the fixing end and the attaching terminal; wherein the locator includes an attached element, a RFID reader, a hall switch, a multiplexer and a microprocessor, the attached element cooperates with the attaching element to guide the attaching terminal and to maintain a stable position relationship between the RFID reader and the RFID responder, the hall switch and the RFID reader are electronically connected to the microprocessor respectively, the RFID reader is electronically connected to the multiplexer, and the multiplexer is connected to a plurality of RFID antennas; wherein when a distance between the attaching terminal of the tag and the attached element of the locator reaches a preset distance, the magnetic element on the attaching terminal triggers the hall switch to send a trigger signal to the microprocessor, wherein based on the trigger signal the microprocessor turns on the RFID reader and meanwhile controls the multiplexer to be connected to corresponding RFID antenna to read the sampled information of the asset stored in the RFID responder.
