The RFID Card is a 125KHz EM4001 compatible card. It has size range of 12-15cm. It helps in delivering the processed data very quickly and in a easy readable format. It is applicable in various fields, such as: Smart access system, Wireless article tracking and DIY projects requiring RFID card based authentication.

The RFID Reader Non IC is a 125KHZ non-contact IC reader and writer. It is widely used for RFID system and project, such as: Automated parking management system, personal identification, access controller, production access control, etc

The RFID Reader Module is a RFID Card Reader Module. It is specially designed for reading code from 125 KHz card compatible read-only tags and read/write card. This module is a very popular for arduino users as I can read 125 KHz EM4100 series RFID card. It has various features like: - Easy to use, Support external antenna, Small outline design, Less than 100ms decoding time, UART interface and many more. It can be suitable for various applications like: - Office/home security, Personal identification, Access control, Anti-forgery, Interactive toy and production control systems etc.

The RFID Reader IC is a RFID Reader MF RC522 Module. It is used in highly integrated 13.56MHz communication card chip to read and write. It has various features like: - Low voltage, Low cost, small size, and Non-contact card chip to read and write and so on. It can be suitable for various applications like:  - Smart home project, Voice broadcast access control system, Attendance punch card system and many more.

RFID identifies by the automatic users. It has a passive tag with proximity-activated chip induction. After electromagnetic induction activation, it returns a code to the system so requires no battery. It has a 125KHz low-frequency radio antenna. It has a keyring format with a plastic body and two metallic rings. It is widely used in homes, offices, parks, and other places. It is applicable to almost all RFID readers.

Each keychain is pre-programmed with a unique ID number and works as a regular 125KHz RFID.

NFC Reader With USB to TTL has a gold-plated PCB which is small in size and also very easy to integrate the user's project. It supports I2C, SPI, and HSU (high-speed UART), and also users can switch between these types of modes. This mini device support RFID read and write and also support P2P peer communication. This device support NFC and android mobile phones. The working distance of this device is 5cm ~ 7cm reading distance. It works in NFC or RFID reader mode. It is ready for compatible use also. It exchanges data with other NFC devices, such as smartphones.

Rfid Reader Rc522 Red card reader is easy to use and low cost too. It applies to the user equipment development, the reader and the development of advanced applications, and the need for the user RF card terminal design/production. It can be directly loaded into various reader modules. Through the SPI interface with simply a few wires, the device utilizes a voltage of 3.3V. It is directly connected with a CPU motherboard so that the module can work in a stable and reliable manner as a distance card reader.

The RFID Card is a 13Mhz EM4001 compatible card. It has size range of 12-15cm. It helps in delivering the processed data very quickly and in a easy readable format. It is applicable in various fields, such as: Smart access system, Wireless article tracking and DIY projects requiring RFID card based authentication.
