Oct 9, 2014 at 18:05 comment added Chris S @user10863 Those pens only work on wood based paper. You can order cotton paper off the Internet or get it at Office Max (people use it for reumes and formal writing all the time), and the pens don't work on it. If I was looking to counterfit money I'd be looking for a retailer that uses pens, probably the easiest target because they're relying on such weak security.
Aug 6, 2013 at 21:56 comment added user10863 In Banff, August 2013, a clerk refused my $50 bill and said it was because there was a report of a local counterfeiter. Someone should tell the Canadians about the pens used in the US to detect counterfeit money. Of course, there's a profit to be made at currency exhange offices, so maybe it's not just the fear of counterfeit money.
