<p>Methods and systems are described for enabling the transfer of one or more digital loyalty stamps from a first user device to a second user device, wherein said first and second user device are in communication with at least one server and a user database configured for storing loyalty stamps that are collected by said first and second user device, a loyalty stamp being associated with a loyalty stamp identifier, a digital image part and a transfer indicator for indicating whether the loyalty stamp is in a transferable or a non-transferable state. The method may comprise receiving a user input via a first touch-sensitive area of a first GUI for selecting one or more first loyalty stamps for transfer to a second user device; rendering a second GUI comprising a second touch-sensitive area for displaying said one or more first loyalty stamps that are selected for transfer and a third touch-sensitive area; and, sending at least one message comprising first loyalty stamp identifiers associated with said first loyalty stamps to said server, wherein said transfer offer message instructs said server to set the state of said loyalty stamps in said user database to transferable.</p> |
