Square is an electronic payment service that is designed to be used for mobile devices. It is a hardware dongle that reads the sound file of a magnetic stripe and parses the retrieved data to obtain the information. Applications have already been released on the markets for Apple and Android so that users in the United States can accept credit cards almost anywhere. This new product does pose a large security risk because a person can obtain the Square dongle for free and it is very small and non conspicuous. Third party programs have already been developed, such as Magread on maemo.org that parses the sound files to display the data on the card.
