The latest design of UK passports, released last year, has a number of new security features: the chip is now hidden within the cover boards, which makes it more difficult to extract and replace fraudulently; the passport number is dot-matrix‐punched through every page; page numbers are both watermarked in the paper and integrated into the collaged pictorial backgrounds which, intaglio printed in fine detail and subtle colour blends, span each two‐page spread. Every background is different, and includes a good deal of microscopic text.
