Canada's new plastic $100 bill features holographic（全息的） elements and a metallic strip running through a transparent window. It's also recyclable.

The thin, shiny, high-tech³, recyclable bill, released Monday by the Bank of Canada, is reportedly almost impossible to rip and thought to be nearly counterfeit⁴（伪造，假装） -proof, according to the bank and news reports. Security features include holographic elements and a metallic strip running through a transparent window.

The new polymer $50 bill goes into circulation in March, with the $20, $10 and $5 bills coming in 2013.

"We've been working with the market for over two years to make sure that ATMs and all banknote-processing equipment are ready for these polymer notes," the bank's scientific adviser⁵, Martine Warren, told The Globe and Mail. "We distributed test notes and advance designs of the genuine notes to machine manufacturers far earlier than we have in the past to make sure that the circulation system is ready for these polymer notes."

On the front of the $100 is a portrait of former Prime Minister Sir Robert Borden (1911-1920). The back "celebrates Canada's contributions to innovation in the field of medicine," the central bank says in its news release.

Canada joins about 30 other countries that have exchanged paper for plastic. Australia was first, in the 1980s.
