Abstract
A card reader configured to read a smart card can be detachably connected to a mobile computing device. When the card reader is attached to the mobile device, an application installed on the mobile computing device permits the mobile device to communicate with the card reader in order to process transactions.Security measures can be used on the mobile device to prevent theft of a PIN during software PIN entry of a payment transaction. The mobile device can prevent the keypad or other input interface from displaying feedback. The mobile device can also prevent passcodes from being stolen by displaying media encoded with digital rights management (DRM) and by managing the media and user inputs at a secure server.A mobile device can securely communicate with a card reader for a payment transaction using asymmetric or symmetric encryption.
