The service is due to go live this week, and users will be able to make and receive payments on their iPhone or Android smartphone, it could end up being a really popular system, and could replace payments for small items like a cup of coffee or a snack.
Once you have made a payment using the square system, your receipt will automatically be emailed to you, giving you a permanent record of all your transactions.
