RFID and NFC Technologies

RFID (Radio Frequency Identification) and NFC (Near Field Communication) are two wireless communication technologies that enable data transfer without physical contact. RFID works by using radio waves to transmit data between RFID tags and readers. These tags can be passive, without a power source, or active, with an internal battery, and are used in applications like asset tracking, inventory management, and access control. On the other hand, NFC is a shorter-range technology, usually up to 4 inches, a subset of RFID designed for secure, quick exchanges between devices such as smartphones and payment terminals. NFC is commonly used in contactless payments, mobile ticketing, and secure access. Both technologies offer efficient and convenient solutions across various industries.
