I have just renewed my British passport, and it contains a very strange sticker. I made a photo of it...
It says "Please remove this label". By feeling and pressing the sticker I do not detect anything underneath it. Holding to the light reveals nothing. The pages behind this page are all blank. There is no explanation in the guidance brochure they sent along with the passport (I am one of those people that reads every word of the guidance). Below the sticker there is some text, if you read paragraph 7 you learn that tampering with a British passport may be actionable as a criminal offence. Incredible to relate, this text is on the same page as the sticker they want you to remove.
Is the purpose of this sticker simply to prove I have examined the passport? Does it replace the wet signature the end user should provide? Or does it flag up if I walk near a scanner? Some kind of electronic signal? If not, what is the purpose of this sticker?
I will be renewing my American passport later this year. Will it have the same thing? Something that needs to be removed where there's no apparent underlying purpose? What are the Americans doing?
I do not know the answer and for reasons not worth exposing here I am reluctant to remove it. Yes, I know I can raise paperwork to the Passport Office for an explanation, but it takes a long time and a medium probability of having to approach the Commissioner to get it resolved. And when their answer finally arrived, there's a very good chance I wouldn't believe it anyway.
Question: what is the purpose of the "Please remove this label" sticker.

There is an existing thread on the net and Nate Eldredge (to whom thanks) provided the link. Some ideas were floated but the thread degenerated into silly conjectures. They didn't nail it down. If it is some sort of progress indicator, why is it not on the cover?
A blog entry discovered by cicto (to whom thanks) presents a credible discussion that the sticker contains an electronic circuit. But when it gets to purpose, the article descends into speculation.
