Context
Radio Frequency Identification (RFID) cards are revolutionising the way we access secure areas, track inventory, and identify individuals. These cards, embedded with tiny microchips and antennas, use radio waves to communicate with RFID readers. This technology, though seemingly simple, is transforming industries and everyday life with its efficiency and versatility. Let’s delve into what RFID cards are, how they work, and their impactful applications across various sectors. RFID cards are embedded with a small microchip that stores and processes information, and an antenna that transmits this information to an RFID reader. When the card comes within range of the reader, the antenna captures the reader’s radio waves and sends back a signal with the card’s data. There are three main types of RFID systems: passive, active, and battery-assisted passive (BAP) .

Analysis
Passive RFID cards do not have an internal power source and rely entirely on the reader’s signal to power the chip and send a response. They are commonly used for access control, contactless payments, and inventory management due to their affordability and durability. Active RFID cards are equipped with their own power source, which provides a much longer read range. They are used in applications requiring real-time tracking, such as in large warehouses or for asset management in hospitals. Battery-Assisted Passive (BAP) RFID cards have a small battery that helps power the chip when in the presence of an RFID reader. This provides a greater range than passive systems without the higher cost of active systems. Also read: What is IT hardware asset management?
