The bar code can be printed as many times as you wish. Use it more than

That's an interesting one, though - the idea of "item has been delivered"
must presumably be done at some sort of final sorting office - it says
nothing about whether an item gets lost between final sorting office and
final destination. In other words, it's still not without flaws.

I don't think delivery comes into it. It's the 'logical franking' that's
the point.

With conventional stamps, they are cancelled by a 'rubber stamp' and at
that point become non-reusable. This doesn't happen on delivery, but at
the initial sorting office. I would guess that barcode scans (and thus
'logical franking') happen at the same time. Whether the item is
delivered or lost is irrelevant in BOTH cases.
