A portable electronic device 3 (e.g. mobile phone or storage device) for processing a secure payment or transaction comprises; memory means for storing payment application software 26; interface means 21 (such as a USB connector) for coupling with a host computer 5; contactless interface means 25 (such as near field communication (NFC) means) for receiving payment token data from a contactless payment token 12; and means 23 for transmitting data over a network 11. When the device is connected to a host computer, the application software is executed, and payment token data is received from the payment token so it may be transmitted to a remote system over the network. The application software is executed from the portable device, but the host computer may be used to display information or receive user input. The host computer does not process the payment, since it may be unsecure or compromised. The portable device may encrypt payment data before transmission. |
