Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Radio-frequency identification comprises interrogators(also known as readers), and tags (also known as labels).
Most RFID tags contain at least two parts. One is an integrated-circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal.
There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery assisted passive (BAP) which require an external source to wake up but have significant higher forward link capability providing great read range.
The EPCGlobal standard (uhfc1g2_1_1_0-standard-20071017.pdf from EPCGlobal) defines four classes of tags as class 1, class 2, class 3 and class 4. Each successive class has higher functionality than the previous one and is also backward compatible. Apart from these four classes, sometimes class 5 is also referred by users in the industry which are nothing but RFID readers.
RFID has many applications, for example, it is used in enterprise supply chain management to improve the efficiency of inventory tracking and management.

RFID attendance system is a technology used to track attendance in various settings such as schools, offices, and factories. It uses Radio Frequency Identification (RFID) technology to identify and track individuals. The system works by assigning each individual a unique RFID tag that contains their personal information, such as their name and employee or student ID number. When the individual enters the premises or a designated area, they can use their RFID tag to check in and out of the system. The RFID tag is scanned by a reader that is connected to a central database or software application that records the individual's attendance. RFID attendance systems offer several advantages over traditional attendance tracking methods such as manual sign-in sheets or biometric scanners. RFID tags are easy to use and can be attached to ID cards, badges, or other personal items that individuals carry with them. The system is also fast and efficient, allowing for real-time tracking and reporting of attendance data. RFID attendance systems can also be integrated with other systems such as payroll and human resource management software, making it easier to manage and process attendance data. Additionally, RFID technology is secure and reliable, providing accurate and tamper-proof attendance records. visit metaguard in to know more about rfid and nfc attendance system
