Advantages of RFID Handheld Terminals
RFID handheld terminals are generally used to read RFID tags. An RFID tag is a radio frequency tag that transmits information through radio frequency. RFID equipment generally uses radio frequency readers, electronic tags, and readers as the main control structure. Compilation and execution of corresponding instructions are completed by sending instructions to electronic tags. Then complete the transmission of information and the reading of tags. Compared with ordinary barcode labels, RFID terminal equipment does not need to contact the identification object during the identification process. The content of the electronic tag can be read only by radio frequency.
The following briefly introduces the advantages of RFID handheld terminal equipment.
1 When reading tags, RFID handheld terminals can read barcodes remotely, and can read barcodes in high-speed motion, in addition to the above-mentioned wireless radio frequency technology without touching the reading object during reading. Take multiple barcodes.
2 It is easy to identify and has high security performance. QR code barcodes are all labels printed on barcode paper or objects, which can be copied. The security and confidentiality of data are relatively poor. RFID technology can encrypt labels, and can encrypt labels. It is directly processed into the packaging or the bottle body, with multiple confidentiality, not easy to be destroyed, and high safety performance.
3 Large capacity, the capacity space of 1/2D barcode is limited, even a QR code with a relatively large storage capacity can only store 3000 characters. The capacity of RFID tags can be controlled according to the needs, and the capacity is very large, so there is no need to worry about the problem of too much data and insufficient capacity.
4. For long-distance and short-distance identification, using barcode scanning guns, the depth of field is generally far and some are close. The far-field depth of field is better for short-distance barcode scanning performance, and the near-field depth of field cannot read long-distance barcodes. This is not the case with RFID handheld terminals.
