Someone passed over This BBC Story on some fancy new tags that contain a silicon chip which can carry a large amount of information and an antenna able to transmit that information to a reading device.
As well as combining a security tag and virtual barcode in one piece of technology, this makes it possible for a book to \"remember\" each transaction, from publisher to wholesaler, retailer to customer and (if the book is sold second-hand) beyond. Similarly, books borrowed from libraries could retain a record of every reader to have perused their pages.
They say the tags would give each book a unique serial number, as well as storing other details such as where it was shipped from and when.
\"It\'s like putting a licence plate on every book, and it means we\'d be able to track the movements of each and every title published.\"
