An RFID reader module (or passive reader module) consists of a reader controller and a radio frequency antenna. The RFID reader module is the core component of the overall radio frequency identification (RFID) system. Automated processes are typically associated with the system. It is used to read and write information from RFID tags. The reader module is generally designed for embedded application such as access control, asset tracking, and other automated processes. The main types of the reader module include SM-M2-MH.

SM-M2-MH Application Field

SM-M2-MH is an ultra-low-power RFID reader module which is designed for reader applications, such as access control, asset tracking and other automated processes. It supports both HF and UHF frequency bands. It has low-power consumption, making it suitable for battery-operated devices. The key features of SM-M2-MH include high reading distance up to 83 cm, power supply range from 2.7 to 5.5 V, 128-bit AES data encryption and anti-collision algorithm. In addition, it supports multiple protocols such as 18000_6B, 18000_6C, EPC C1G1, EPC C1G2, EMCT, and ISO15693/ISO14443A and ISO18000_3M3.

Working Principle of SM-M2-MH

The main principle of an SM-M2-MH reader module is based on the contact less communication between an antenna and a tag. The antenna transmits an interrogating signal to the tag, and the tag will reproduce the data stored in its memory and it will send it back to the antenna. It works in two modes namely active and passive. In active mode, the antenna transmits the data to the tag and will receive the response from the tag. In passive mode, the antenna just receives the data from the tag. The system will analyze the data it received and it will make decisions based on the defined rules.

Basically, RFID technology can be used to identify objects and objects carrying RFID tags and can be tracked using the RFID reader. The reader module contains an antenna and a processor. The antenna captures the radio frequency signals containing the data coded on the tag and transmits it to the processor, which reads the data, verifies it and then stores it into a database. The antenna of the RFID reader module must have suitable directional, polarization, gain and discrimination to receive the data from the tag.

The RFID reader module has been developed to be very robustly designed, and its low power consumption and higher reading ranges make it a cost effective and reliable solution for embedded applications. In addition, the reader module supports many protocols (such as ISO 14443A, ISO 14443 B, ISO 18000-3M3, etc.) and can be easily integrated into different types of systems. It can also be programmed for custom applications.

The main advantage of the SM-M2-MH is its low power consumption. It requires very small amount of power for operation and it can be safely used in battery operated applications. In addition, it has a high read range up to 83 cm. It is also capable of supporting multiple protocols and can be easily integrated into various systems. In addition, the reader module also has an anti-collision algorithm, which prevents multiple tags from being read at the same time.

In conclusion, SM-M2-MH is an ultra-low power RFID reader module which is designed for reader applications, such as access control, asset tracking and other automated processes. It has low power consumption, high reading distance, and supports multiple protocols, making it suitable for various applications. It also has an anti-collision algorithm, which prevents multiple tags from being read at the same time, and can be programmed for custom applications.
