Electronic tag compared with the traditional barcode printing devices _ a question
Compared with the traditional bar code identification technology, RFID has the following advantages: 1. Rapid scanning a bar code can only have a bar code to accept to scan; RFID readers can be read at the same time identify several RFID tags. 2. Small size, shape, diversification of RFID on the reading is not limited by the size and shape, precision don't need to read and to cooperate with fixed size and quality of printing paper. In addition, the RFID tag changes can develop toward miniaturization and diverse forms, so that applied to different products. 3. Pollution resistance and durability as the carrier of the traditional bar code is paper and therefore more vulnerable to pollution, but RFID for materials such as water, oil and chemicals has a strong resistance. In addition, because the bar code is attached on the plastic bags or outer packing carton, so more vulnerable to wreck; RFID data volume label is the existence of chip, therefore can from fouling. 4. Reusable cannot change after today's bar code printing up, RFID tags can be repeated to add, modify, delete, RFID data volume label in storage, convenient information update. 5. Penetrating and no barriers of reading in the case of covered, RFID can penetrate paper, wood and plastic etc. Nonmetal or opaque materials, and the communication ability of penetrating. And bar code scanner must stop at close range and no object, can read the barcode. 6. Data memory capacity of the large capacity is 50 bytes of one-dimensional bar code and two-dimensional bar code of the largest capacity can store 2 to 3000 characters, RFID's largest capacity is several MegaBytes. With the development of the carrier of memory, data capacity there is also a growing trend. Future items needed to carry data quantity will be more and more big, the volume label can expand capacity demand also increases accordingly. 7. Security due to the bearing of RFID is electronic information, through the data content can be password protected, that its content is not easy to be forged and altered. In recent years, RFID because its have read over a long distance, high storage features and high-profile. It not only can help an enterprise greatly improve the efficiency of goods, information management, also can let the sales and manufacturing enterprise interconnection, thereby more accurately receive feedback information, demand information, optimize the entire supply chain.
