Stamps update

Got the stamps replaced today, only eight days after posting which isn't bad considering how busy they must be. The new stamps are about 50% bigger than the old one even without the code (it's a narrow strip of QR code, not bar code, my bad for the error) and total width with the code strip is about twice that of the old ones.

Each has a different code, it appears to be possible to detach it from the stamp, not sure why.
