RFID (Radio Frequency Identification) and NFC (Near Field Communication) are both technologies used for wireless communication between devices over short distances.
RFID (Radio Frequency Identification):
Definition: RFID is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information.
Working Principle: RFID tags are typically small, passive devices that can be attached to or embedded in objects. They contain a unique identifier and sometimes additional data. RFID readers emit radio waves to interact with these tags, allowing them to read the information stored on them without requiring direct line-of-sight or physical contact.
Applications: RFID is used in various industries for asset tracking, inventory management, access control, and contactless payment systems.
Passive RFID (Radio Frequency Identification) refers to a type of RFID technology where the RFID tags do not have an internal power source or battery. Instead, they rely on the electromagnetic energy emitted by an RFID reader to power them and to transmit data.
NFC (Near Field Communication):
Definition: NFC is a subset of RFID technology that enables two devices (or a device and a tag) to communicate with each other when they are brought within a few centimeters of each other.
Working Principle: NFC operates at 13.56 MHz and allows for communication between devices in peer-to-peer mode or between a device (like a smartphone) and an NFC tag. It can read and write data on compatible NFC tags, facilitating interactions such as mobile payments, data exchange, and pairing electronic devices.
Applications: NFC is widely used in contactless payment systems (e.g., Apple Pay, Google Pay), public transport ticketing, electronic access cards, and smart posters.
