Radio frequency has been transformed from obscurity to mainstream application that helps speed up the manufacturing process of products and materials. A few years ago, RFID was considered from a supply chain perspective. But today RFID is used in various ways without us realizing it. RFID (Radio Frequency Identification) is a system for reading information and automating the identification of an object or person using radio waves. RFID uses multiple radio frequencies and many types of tags with different communication modes and power sources. Say no to plagiarism.

Get an Original Essay RFID systems consist of 3 components; a transceiver (RFID reader), a scanning antenna and a transponder. The transponder is the RFID tag consisting of microchip, antenna and case that has been programmed with information, and the scanning antenna emits the radio frequency signal in a relatively short period of time. It provides a means to communicate with the transponder and provides the communication energy to the RFID tag in the case of the passive tag. Passive RFID tags require energy transfer from the reader via radio frequency which does not require batteries and the communication range is very short. Active RFID tags have their own power source and these tags can still receive the signal even if the reader is located further away. Sometimes called semi-passive or semi-active, battery-assisted passive tags (BAPs) are virtually passive RFID tags that combine important active tags. To power the chip, BAP tags typically use an integrated power supply, usually a battery, and the energy captured by the reader can then be used for backscattering. When an RFID tag enters a red zone of the scanning antenna, its data is captured by the reader that activated the microchip and sends the microchip information to a host computer or programmable controller for action. Almost all libraries around the world use RFID tag to tag books. According to CEO Lim Peck Hui of Tunity Technology, “When it comes to labeling or tracking items, RFID works better than barcodes and QR codes as multiple RFID tags can be read remotely in an instant, so data is acquired quickly." RFID systems can improve the ability of staff or customers to discover the location of books. When comparing barcode systems with RFID systems, RFID systems can read multiple tags more than 100 at the same time, but the barcodes can only be read one at a time manually. Additionally, barcode scanners must read the barcode directly, while RFID tags do not need to be placed in line with the scanner and can be scanned or read further away than the barcode. The data in the barcode printed on the sticker must be clearly visible so that it can be scanned easily. The label display can be easily damaged due to weather or other reasons and forgery becomes easier while RFID does not suffer from all this because it does not require sight and its electronic nature allows that data can be encrypted for avoid any data leak. information.
