A mobile communications device is configured for near field communications, "NFC", with an NFC interface module of a transaction terminal system. In response to interfacing the mobile communications device with the transaction terminal system, information can be exchanged between a mobile application on the mobile communications device and the transaction terminal system. The information exchanged can include at least one of information held by the transaction terminal system that is indicative of a terminal system currency of the transaction terminal system and information held on the mobile communications device that is indicative of a user currency. The transaction terminal system or the mobile application can be operable to compare the terminal system currency to the user currency, and where there is a difference, to cause a currency choice offering to be displayed on a display of the mobile communications device. In response to user selecting the user currency a transaction can be performed in the user currency. |
