Communication system, a method of initiating a transaction, a base station and a transponder

A communication system for initiating a transaction between a contactless smart card and a reader, the communication system comprising:

• a contactless smart card having a wireless communication interface and a display device;
• and
• a reader having a wireless communication interface and a user input device;
• wherein the contactless smart card and the reader are configured to wirelessly communicate a transaction initiation code between each other;
• wherein the contactless smart card is configured to display the output information on the display device, the output information being based on the wirelessly communicated transaction initiation code;
• wherein the reader initiates the transaction between the contactless smart card and the reader only if compatibility is discovered between the transaction initiation code and user information received from a user via a manual input at the user input device.

A method of initiating a transaction between a contactless smart card and a reader, the method comprising the steps of:

• wirelessly communicating a transaction initiation code between the contactless smart card and the reader;
• displaying output information on a display device of the contactless smart card, the output information being based on the transaction initiation code;
• after the output information is displayed on the display device of the contactless smart card, receiving a manual input of user information by a user of the contactless smart card at an input device of the contactless smart card;
• and
• initiating a transaction between the contactless smart card and the reader only if compatibility is discovered between the transaction initiation code and the user information that was input at the input device of the contactless smart card.
