What I've learnt: Ann Cairns
Today I'm working at MasterCard, which is a long way from a shrinking business. Innovation is important to us and we're currently working with the United Nations World Food Programme. They deal with 90 countries across the world, trying to get food to the people who need it the most. In only five per cent of the cases do they actually get money into people's hands so they can buy food. The rest of the time they're moving food around. We're developing what we call digital food, an electronic voucher system where the vouchers can be used in special World Food Programme approved shops to buy food.
