Yep, maybe he thought that was a card reader. I've used WAY more handheld card readers than I have handheld barcode readers. Like I said, maybe 5 times max have I used a handheld barcode scanner. I don't know I would instantly recognise it any quicker than the 1s or whatever it is he holds it up for?
No it's just clear he's not had to do it himself and the people in charge of this country are so out of touch they look out of place doing 'normal' things.
