New submitter Selena Larson writes: The United Nations World Food Programme (WFP) rolled out a pilot program for refugees this week that connects biometric data directly to points of sale and enables people to buy groceries with an iris scan. The computerized system communicates with the United Nations refugee agency, UNHCR, which keeps a database of biometric data collected from refugees around the world. If the individual is confirmed to be a refugee in Jordan, based on their iris scan, a bank the organization works with approves the transaction.
The best book on programming for the layman is "Alice in Wonderland";
but that's because it's the best book on anything for the layman.
