RFID uses radio waves to automatically identify objects. It is used widely in supply chains to reduce costs through improved tracking and coordination. RFID tags can store more information than barcodes and be read from a distance without line of sight. Common applications of RFID include use in libraries to track books, in warehouses for inventory management, in healthcare for tracking patients and equipment, and in livestock farming for animal identification.
RFID and its Applications
- 1. RFID and Applications RFID or Radio-frequency identification •is the use of wireless non-contract system that use radio-frequency electromagnetic fields to transfer data from a tag to a receiver. •The automatic identification and data gain the large contribution to many companies bottom line. The RFID is one of the most wanted technologies that usually appear in the large successful enterprises, such as Wal-Mart, Dell, food stores, automobile part makers, computer stores, and even book stores. •of RFID offers attractive avenues as to reduce the cost through coordination between marketing and manufacturing across supply chains. It could improve supply chain efficiency through real-time tracking, safety monitoring, and overall warehouse operations, which the results leads to increase in sales volume and improving profitability for suppliers and retailers.
- 2. How it work • It emitted as two-way radio transmitter receivers which the readers send a signal to the tag and read its response . • The information stored electronically in a non-volatile memory. This possibly will be an unique tag serial number, or product related information • Tags may either be read-only which factory assigned serial number that is used as a key into a database, or may be read/write where object-specific data can be written into the tags by the system user
- 3. RFID type • Active RFID : have on-board battery and frequently transmit its ID signal • Passive RFID: does not require the battery, which it much cheaper and the size of it can be small RFID Active Tag RFID Passive Tag
- 4. RFID and Barcodes • The barcode has become a component that could easily be found on the product that you buy. • The barcode is the ubiquitous standard for identifying and tracking products. • The system was based on the ink pattern that glowed when exposed to ultraviolet light, proved to be unstable in practice to be commercialized
- 5. The advantages of RFID • Each RFID tag could have an unique code that allow every tagged item to be individually • RFID allows for information to be read by radio waves from a tag without requiring line of sight scanning or human intervention • RFID allows for virtually simultaneously and instantaneous reading of multiple tags • RFID tags can hold far greater amounts of information which can be updated • RFID tags are far more durable
- 6. RFID Application Library System : The technology use the passive tags instead of active tags. The tags that use in the facility requires a very short read range and the data that stored on the RFID tags does not reveal any important information The information that usually recorded on the RFID will be the ‘book name’, ‘author of the book’, ‘date of publishing’, ‘unique identification number’
- 7. Warehouse System & Supply chain : • The technology can be used to identify, track, sort or detect a wide variety of objects. The data of tags can change or add new information always • The main objective of these was to reduce the cost and increase it efficiently on working process such as substitute on the paper-based work.
- 8. Healthcare : The technology are used for tracking people or items in a facility, locating staff or instruments in a hospital, keeping track of patients in care facility.
- 9. Card Technology : The technology used wireless computer chip and antenna based and contactless smart-card technology in order to identity the specific information of each credit card. • The credit card is designed specifically for easy integration into the existing payment-authorization infrastructure. The technology are fast, easy, often more reliable than magistrate transactions • The RFID credit technology is absolute security and privacy
- 10. Animal Identification : The microchip implant is an identifying integrated circuit which placed under the skin of animals . Each chip ID will consist of owner contact information • The farm management system involve in fully automated process such as feeding, weighing, disease management, and breeding practices. Each ear tags that be used in livestock have conform international standards ISO 11784 and ISO 11785
