Questions tagged [pairing]

Bonding of two devices, eg two smartphones, or a computer and keyboard. Term is commonly heard in combination with Bluetooth. When pairing successfully completes, a bond forms between the two devices. This enables those two devices to connect to each other in the future without repeating the pairing process to confirm device identities. When desired, the user can remove the bonding relationship.
