　　Regardless of barcodes or QR codes, only one tag content can be read at a time, while using RFID technology, multiple tags can be read at a time, and the reading efficiency is greatly improved. This is an advantage of RFID, and because of this advantage, it is used in many Occasion replaces barcodes. RFID has different frequencies, which can be divided into low frequency (125Khz~134Khz), high frequency (13.56Mhz), ultra-high frequency (860MHz~928Mhz), microwave (2.45Ghz, 5.8Ghz) ). The higher the frequency, the longer the propagation distance, but the less diffracting or penetrating ability.

　　The RFID tag can repeatedly add, modify, and delete the data stored in the RFID tag to facilitate the update of information. In the case of being covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can carry out penetrating communication. Barcode scanners can only read barcodes when they are at close range and not blocked by objects.

　　RFID cost introduction

　　RFID tags contain chips, which are naturally more expensive than barcodes and QR codes. RFID tags can be divided into those without power supply and those with power supply, and the cost with power supply is higher than that without power supply. The RFID handset can read the content of the RFID chip, and can also write information into the chip. Its price is also higher than barcode, QR code handheld. When the RFID handheld is used, it can be used alone, and then the purchase data is transmitted to the computer. RFID also has an RFID reader that must be connected to a computer
