RFID Tokens
RFID tokens are physical devices that use Radio-Frequency Identification (RFID) technology to store and transmit data wirelessly via radio waves for identification, authentication, or access control purposes. They typically consist of a microchip and an antenna embedded in a small, portable form factor like cards, key fobs, or tags. In development contexts, they are often integrated with software systems for secure entry, asset tracking, or payment processing.
Developers should learn about RFID tokens when building systems that require physical authentication, such as secure building access, inventory management, or contactless payment solutions. They are particularly useful in IoT applications, logistics, and security systems where automated, non-contact identification is needed to enhance efficiency and reduce manual errors.
