RFID Electronic Ticket Overview:
RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification. RFID electronic tickets are based on RFID technology, new tickets. RFID electronic ticket is the core of a high-security integrated circuit chip design and production of high RFID tag threshold, the world's only electronic ID tag curing in the chip, can not be modified, imitation; no mechanical wear, anti-fouling; Tickets In addition to the unique ID number, tickets in addition to password write protection, the data part of the available encryption algorithm for security management.
The most basic RFID system consists of three parts:
1. Tag (Tag: RF card): The coupling element and chip components, the tag contains a built-in antenna, and radio frequency antenna for communication.
2. Reader: Read (in the read-write card can also write) the label information device.
3. Antenna: Transmit RF signals between the tag and the reader.
Some systems are also connected to an external computer (host computer system) via the RS232 or RS485 interface of the reader for data exchange.
Hand-held ticket machines and RFID tickets through wireless transmission mutual password authentication, that is, the organizers in the RFID tickets, ticket machines to write the same password, only to write a password ticket to pass the ticket machine verification, handheld ticket machines Without the need for alignment, contact, verify the speed of 0.03 seconds; check when the ticket officers, the effective vote was green, ringing at the same time the screen display, fast and accurate ticket valid votes; RFID tickets can record entry and exit of the entrance, To prevent the ticket was stolen delivery again.
Performance characteristics
1. Quick scan. RFID reader can simultaneously read and read several RFID tags!
2. Small size, shape diversity. RFID is not limited by the size and shape of the reader, and does not require a fixed size and print quality for the reading accuracy. In addition, RFID tags can be miniaturized and diversified forms of development to apply to different products.
3. Anti-pollution ability and durability. The traditional bar code carrier is paper, so susceptible to contamination, but RFID on water, oil and chemicals and other substances have a strong resistance. In addition, because the bar code is attached to plastic bags or packaging cartons, so particularly vulnerable to damage; RFID tag is the data stored in the chip, so you can avoid contamination.
4. Reusable. Today's bar code printing can not be changed after printing up, RFID tags can be repeated to add, modify, delete the RFID tags stored in the data to facilitate information updates.
5. Penetration and barrier-free reading. In the case of being covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and is capable of penetrating communication. The bar code scanner must be in close proximity and no object to block the case, before they can read the bar code.
6. The memory capacity of the data is large. One-dimensional bar code capacity is 50Bytes, two-dimensional bar code maximum capacity can be stored from 2 to 3000 characters, RFID maximum capacity there are several MegaBytes. With the development of the memory carrier, the data capacity has been expanding. The amount of data needed to carry the future items will be more and more, the label can expand the capacity of the corresponding increase in demand.
7. Security. Because RFID carries electronic information, its data content can be password protected, so that its content is not easy to be forged and altered.
RFID because of its long-range read, high storage and other characteristics of high-profile. It can not only help a company to improve the efficiency of the goods and information management, but also can make the sales enterprise and the manufacturing enterprise interrelate, so as to receive the feedback information more accurately, control the demand information and optimize the whole supply chain.
