> I wish they would give you the option to pair through USB. Just plug in the host and peripheral and press the pair button, and it should automatically negotiate pairing.
This is called "Out of band" (OOB) pairing and supported since Bluetooth 4 iirc, it's a method which allows key exchange using a different bearer than Bluetooth.
It's implemented quite famously on the Sony Playstation 3 and 4, where BT-pairing is done by connecting via USB and pressing the "Playstation" button.
On other Bluetooth-devices it's mostly not implemented because apart from the limited support for OOB pairing over USB on the host-device, it would require the peripherial device to also have a USB data-interface in control of the Bluetooth chipset.
So more complexity and cost, to solve a problem which barely exists anymore.
I think maybe there's like on one or two people who have gotten neard daemon doing Bluetooth OOB with Bluez, but it's very obscured in results or their reports have bit rotted off the net.
You can try an Android App like NXP TagInfo to read the contents of that Tag and show you what's inside of it, my expectation is that it's just a basic NFC Tag...
