A computer server system comprises a communications module; a processor coupled with the communications module; and a memory coupled to the processor and storing processor-executable instructions which, when executed by the processor, configure the processor to receive, via the communications module and from a requesting device, a signal that includes a request to send a stored-value card to a recipient, the request identifying one or more parameters of the stored-value card; generate the stored-value card and a three-dimensional object representing the stored-value card according to the one or more parameters; and send, via the communications module and to a mobile device of the recipient, a signal that includes the three-dimensional object representing the stored-value card for display in augmented reality.
