<h2>Introduction to RFID Card 13.56 MHz</h2>
RFID (Radio Frequency Identification) technology has revolutionized how we track, identify, and manage assets across various industries. Among the different frequencies used in RFID systems, the 13.56 MHz frequency stands out as one of the most widely adopted standards globally. An RFID card operating at 13.56 MHz is a contactless smart card that utilizes high-frequency (HF) radio waves to communicate with readers. These cards are embedded with a microchip and an antenna, enabling seamless data transmission without physical contact. The versatility, security, and efficiency of 13.56 MHz RFID cards make them indispensable in applications ranging from access control and payment systems to inventory management and public transportation.


<h2>How 13.56 MHz RFID Cards Work</h2>
The operation of an RFID card at 13.56 MHz is based on electromagnetic induction. When the card comes within the proximity of an RFID reader (typically up to 10 cm), the reader's antenna emits a radio frequency signal that powers the passive RFID card's integrated circuit (IC). This energy harvesting process eliminates the need for an internal battery in the card. Once powered, the IC modulates the signal and transmits stored data back to the reader. The 13.56 MHz frequency is part of the HF band, which offers a good balance between read range, data transfer speed, and resistance to interference. Key standards governing this technology include ISO/IEC 14443 (used for proximity cards like MIFARE and DESFire) and ISO/IEC 15693 (used for vicinity cards), ensuring interoperability and reliability across devices.


<h3>Components of a 13.56 MHz RFID Card</h3>
A typical RFID card operating at 13.56 MHz consists of three main components: the microchip, the antenna, and the substrate. The microchip, often made of silicon, contains memory (e.g., EEPROM) to store unique identifiers (UIDs) and other data, as well as logic circuits for processing commands. The antenna, usually a coiled copper wire, is crucial for receiving and transmitting signals. The substrate, commonly PVC or PET, encapsulates these elements, providing durability and flexibility. Advanced versions may include encryption modules for enhanced security, such as AES or DES algorithms, to protect ag The Use of RFID for Human Identity Verification
