Data collectors are devices used to perform all mobile operations. They allow you to identify and collect information without using a desktop computer. Most often have their own software that allows you to implement selected tasks. They use a touch screen or a screen and a built-in keyboard to communicate with the user. To easily capture and identify information, they are equipped with built-in code readers, RFID readers, and digital cameras. For data exchange and connection with other devices, they use WLAN, Bluetooth® or cable connection, eg using a docking station.
