RFID (Radio Frequency IDentification, radio frequency identification) - a method of automatic identification of objects, in which data is read or written by means of radio signals, stored in RFID cards. The reader is used to read information from cards or tags of radio frequency identification (RFID) type EM4100, EM4001 (and other compatible) with frequency 125 Input voltage. The card reader can be used in access control systems, automatic identification, robotics, etc..

Practical application: automatic lock to open the door, drawer, closet, organization of warehouse accounting, etc..

To use the card reader, you need to connect it to your computer using a USB cable.. After connecting to the computer, the red LED on the reader body should light up and a single beep will sound. After that, your computer's operating system should start searching for and automatically installing drivers.. If the operating system could not install the drivers automatically, you need to do it manually (the card reader is compatible with Windows 95/98/ME/2000/XP/Vista/Seven operating systems).

The card reader is installed in the system as a HID keyboard. Now you can check the reader: open any simple text editor in your operating system and bring a compatible RFID card with information to the contact area of ​​the card reader at a distance 3 – 5 cm. A single beep should sound., and the data from the map will be displayed in a text editor. The card reader is powered from the computer's USB port..
