Overview

MFRC52202HN1,115 (MFRC522 for short) is a component of the RF Access, Monitoring ICs product family by Philips Semiconductor. It is designed to work as a contactless reader/writer to enable secure authentication and communication for various applications in the identification and access control markets. It works as a contactless reader-writer via radio-frequency (13.56 MHz frequency band) and a contactless IC card and is also backward compatible with the ISO/IEC 14443 Type A and MIFARE standards.

Application Field

MFRC522 is specifically designed for systems that utilize radio communication for authentication, identification, personal authentication and access control. It is used in a wide range of applications such as access control, secure authentication, payment systems, loyalty programs, and public transport. It is also often used for the secure storage and encoding of "data" cards such as tickets, keys, and IDs.The applications of MFRC522 in Access Control include Vehicle Access Control systems, Building Access Control systems, Security Systems, POS systems, and Self-service Machines. In Personal Authentication, it is used for biometric authentication (e.g. fingerprint or iris-scanning) and for authentication through contactless cards like NFC-enabled IDs, Contactless Payment cards, and Smartphone Apps.

Working Principle

The working principle of the MFRC522 is quite simple. It comprises two main components, the reader and the antenna. The reader is responsible for providing energy to the card, while the antenna acts as a link between the card and the reader. Once the card is placed onto the reader, it initiates communication between the reader and the card by sending out a signal via its antenna. This signal is then received by the card’s antenna, which in turn, transmits a response back to the reader. Upon receipt of this response, the reader then sends out a data frame consisting of the commands that the card should execute. The card then responds with the results of the commands.The MFRC522 IC provides multiple levels of security and integration, making it very secure. It is also optimized for both low-power consumption and high speed, making it ideal for applications which require both speed and security. Additionally, it supports the integration of various encryption algorithms, which further increase the security of communication between the reader and the card.

Conclusion

The MFRC52202HN1,115 is a perfect example of a secure access, monitoring IC designed for contactless applications. It is optimized for both low power consumption and high speed, making it perfect for applications that require both speed and security. Additionally, it supports multiple levels of security and integration, thus providing a secure communication between the reader and the card.
