125kmz and 13.56MHz Ttl Interface Contactless RFID Card Reader Module

125KMz and 13.56MHz TTL Interface Contactless RFID Card Reader ModuleOverview: RCR-3700 card reader is a standard module based on IEC/ISO14443-A protocol and 125KHZ dual frequency band. It has the characteristics of plug and play, rich communication interface, etc. At the same time, the serial port communication also supports active card reading (reading when the card is close to it) and passive card reading (sending instructions to read the card), card number format switching; the module comes with a single-chip control without secondary Programming can be seamlessly connected to various operating systems. It can be widely used in cloud intercom systems, charging piles, electronic shift signs, one-card applications, automatic vending, conference sign-in, information entry, and many industries in the field of commercial display to meet different user application scenarios. 13.56MHz and 125KHz RFID Card Reader Module with TTL Interface is an embedded contactless RFID card reader module that supports both 13.56MHz and 125KHz frequency bands. The module adopts TTL interface connection, which can communicate with computer or other equipment conveniently. This module supports the RFID reader function of two frequency bands, and the appropriate frequency band can be selected for reading according to the application scenario. The module is equipped with a high-speed reader engine that can efficiently read and write information from RFID cards.Specification: StandarduEM + ISO14443-AInterfaceUSB, TTL, RS232, RS485, Wiegand 26/34Contactless cardEM/S50/S70/F08/ NtagOperating VoltageDC3.3-5VReading distance0 ~ 5cmRead time
