Connecting to a host device consists of two distinct processes.
Pairing: The scanner pairs with the device, exchanging security information. Pairing information is stored in the scanner's memory, and the two devices are associated with one another.
Connecting: The scanner connects to the device. Connection allows the devices to communicate and send data back and forth.
A scanner may disconnect from the host device for a variety of reasons. A disconnected scanner is still paired with the device. You can manually scan/tap to reconnect the scanner to the paired device.
