Smart Card and Rfid Tag

The Origin of Contactless Smart Card

Radio frequency identification system for major manufacturers to provide all dedicated system, lead to different applications and different industries with different manufacturers of frequency and protocol standards, this confusion and separatism situation has hampered the whole RFID industry growth. Many American organizations are to begin to address this problem, and have already made some achievements. Standardization of radio frequency identification technology will stimulate substantial development and wide application of. The contactless smart card is based on the whole process of logistics management, reduce costs and improve service levels for two purposes. How to correct cost and conditions to ensure the right customers at the right time and place, and get the right product to become the logistics enterprises in the pursuit of the highest goal. Therefore, mastering the inventory of the quantity, morphology and distribution, improve the inventory of liquidity has become the core content of the logistics management.

Rfid Laundry Tag in General

In general, the enterprise inventory value to enterprises accounted for about 25% of total assets, total current assets of enterprises more than 50%.So the logistics management of heart is supply chain inventory management. In the transportation management of the use of radio frequency identification technology, we need only on goods packaging on the installation of electronic tag, in transport checkpoint or transit station set reader, can realize the visualization management of assets. In the process of transportation of rfid laundry tag, electronic label reader information via satellite or telephone lines to transmit to the transport sector database, electronic label each through a checkpoint, database data is updated, when the electronic label to reach the terminal, database shutdown. At the same time, the owner can be according to the authority, access in-transit visual webpage, understanding the specific location of the goods to improve the service of logistics enterprise has important significance.

The Working Principle of UHF Rfid Tag

The basic working principle of RFID technology is complex: the label into the magnetic field, receiving the reader sends RF signal, by virtue of induction current was obtained by the energy stored in the chip to send out product information in the Passive Tag, passive tag, label or by active sending signals of a given frequency, interpretation for reading information and after decoding, is sent to the central information system for data processing. The uhf rfid tag is produced in this technology. A complete set of RFID system, is a reader and tag the so-called transponder and application software system of three parts, its working principle is Reader launch a specific radio frequency energy to the Transponder, to drive a Transponder circuit internal data sent, then Reader is sequentially receives interpretation data for the application, and make corresponding treatment.
