A British vacation (but I'm also going to Japan)

Is that the customs exit codes? (Kind of like the go to lane 1/2 etc here in Australia).

Also I've dine TPP shopping without the QR code. You just have to tell them a few times that it's not in your passport anymore which is confusing on my passport as at any given time i should have "an active" JP immigration QR sticker.

Immigration, not customs. This was before we even got to the immigration counters.
But no idea really since they never came up again! And mother and I were allowed to go as a group even though we had different codes.

Edit, to add a bit more info. So after getting off the plane we used these new machines first. Seemed to me like they were handling the VisitJapanWeb info (and fingerprints), which previously was done by staff at counters.

Oh I know it can be done with JTPP card, I did it quite a few times last trip. Some sales persons in Tokyo actually knew them!
But most had no idea and it cost me quite some time....My Japanese were also not good enough to explain this thingy clearly....
