I’m Martine Warren and I’m a Bank Note Design Specialist with the Currency Department at the Bank of Canada. Our polymer notes are technical products as well as design products. So, I work with printers and designers. But I’m also a chemist and I work with engineers and physicists. We had to develop all kinds of new tests in order to ensure the durability of the new Canadian polymer bank notes. We put them in boiling water and used dry ice on them to make sure they could withstand our cold Canadian winters. When we are developing new designs we work very closely with the partially sighted. We bring them in and we do focus groups so that they can look at our very early concepts and tell us which ones are the most accessible. I’m Diane Bergeron. I am a Canadian who is totally blind and I work at the Canadian National Institute for the Blind. Like most people, I use cash in my day to day life. I have had incidents where I have been given cash back and exchange my change at the counter, and didn’t know until I got home that I had been given the wrong money. I like the tactile features which they have on the Canadian bills in the top corner; they’re on top corner of the bill. And I use that when I’m spending money in Canada, because it makes it easier for me at the counter to be able to know which bills I’m providing and which change I’m getting back. When I travel, there’s a lot of countries that don’t have tactile features on their bills, which makes it difficult for me to identify the bills in my wallet, so I need to fold the bills in different ways to keep track of them. I work on a number of very interesting projects with my colleagues, for instance a security feature that changes colour when you squeeze it, and another security feature that makes it so that bank notes light up when you hold them in the palm of your hand.
