  1.1 background
  Our country is a food production and consumption, with the development of market economy and improvement of living standards, meat, vegetables have become important urban and rural residents of basic necessities. In recent years, the Party Central Committee and the State Council attach great importance to, Chinese meat vegetable safety level is significantly increased. However, meat vegetable production and circulation of the low level of organization, relatively backward technology, cable card ticket, purchase ledger system lacks, management is difficult, still many quality and safety risks. In recent years, meat vegetables, food security event occurred, introduction using information technology achieved cable card cable votes, and purchase and sale Taiwan account of electronic of, established meat vegetables circulation dates back system, do circulation node information interconnected Exchange, formed full of circulation information chain and responsibility dates back chain, conducive to improve circulation subject of security responsibility consciousness, strengthened prevention measures, formed tracing Chase accountability mechanism, created assured meat dish channel brand; conducive to consumers query and activist, improved consumption expected, promote consumption; Found in favour of enhanced government departments on issues of food and processing capabilities, improve food safety and standards of public service: it is beneficial to promoting the improvement of the modern circulation system, raise the level of market operation regulation: to raise the producer in accordance with food safety standards in the production process, from the source to improve product quality and safety level.
  1.2 application introduction
  1.2.1RFID technology
  RFID technology (Radio Frequency Identification,RFID) is a non-contact automatic identification technology, and get it via radio waves to automatically identify the target object data information, identify without manual intervention, which can identify multiple target objects, working in a variety of harsh environments, operation is quick and easy.
  RFID system:

        Reading device through launches antenna sent must frequency of RF signal, dang electronic label into launches antenna work regional Shi produced induced current, electronic label get energy was activated; electronic label will itself coding, information through card built-in sent antenna sent out: System received antenna received to from electronic label sent to of carrier signal, by antenna regulator transfer to reading device, reading device on received of signal for demodulation and decoding then sent to Taiwan main system for related processing: main system according to logic operation judge the card of legitimacy According to different corresponding to the set of management and control, issued a directive signal control executing agency action.
  Based on the different e-label power supply, electronic tags can be divided into active and passive tags, active tags with a battery, passive tags have no battery. According to the energy supply pattern, RFID-systems
  For active and passive: according to the working frequency, RFID systems are low frequency, medium frequency, high frequency, UHF, microwave and radio frequency, and so on. Meat vegetable circulation industry in modern information management systems, requirement management of no paper, order, standardization, intelligent features. RFID smart labels, waterproof, anti-magnetic, anti-static, wear-free, large storage capacity, use of a sign, easy operation, into a modern meat vegetable circulation information management the most ideal solution. As a carrier of information, comparison of RFID and bar code has the following advantages
  Select RFID as the main carrier of information storage platform, based on the following considerations:
  1. convenient operation: read and write RFID data is done through a private read-write device, non-contact, distant
  2. not subject to environmental impact: particularly suitable for meat vegetable circulation industry

  1.2.3 smart card technology
  Smart cards are also called CPU cards, contact and non-contact cards, microchip embedded CPU. CPU card chip contains informally refers to the chip-microprocessor, it functions as a micro-computer. People often use integrated circuit card (IC card) on the metal sheet is the CPU card chip. CPU cards can be applied to the financial, insurance, police, Government and other fields, with user-space, read faster, supporting features such as a multi-purpose card, and has passed the certification of the PBoC and commercial secrets. CPU cards from the appearance and General IC card, RF card did not differ, but a huge boost in performance, security, and General lC card, to improve a lot, usually CPU card contains a random number generator, hardware DES,3DES cryptographic algorithms, coupled with operating system is OS, also known as COS, you can achieve the level of financial security.

  1.3. system overview
  Meat vegetables circulation dates back system platform is set information collection, and electronic label application, and multi-channel query for based, while combined food security management system, and related certification system and circulation food security management approach of related spirit, design established of a feasible, and perfect, can for meat vegetables planting/farming, and production, and processing, and sales, link provides full, and-body of of technology and the application support of management platform.

  1. global monitoring, every aspect of the entire chain from food sources to the table for the real-time detection;
  2. automatic identification, using RFID technology, automatic identification of different segments of the production and circulation of information, by means of fixed or handheld readers to automatically link production and distribution information.
  3. traceability, tracking food throughout the production process, and centralized backup to the data quality Center, provide traceability information to Governments and businesses.
  4. Security, with new-generation RFID passive tag, identify quick response time, and average failure rate is low, you can make sure that the label identification security, timeliness and stability.
