Observing the holy month of Ramadan is a custom which dates back hundreds of years, but technology is starting to change the behaviour of those taking part. Charities and companies are increasingly looking to gather donations and boost sales online during the annual fast, as Jonathan Frewin explains. (..) "There are increasing signs that technology is beginning to play an important role as well. These cartons of food are destined for developing countries all over the world, and the United Nations World Food Programme which coordinates this warehouse, is running an online campaign this Ramadan to gather funds. The key to it is an online payment system," says Frewin.
