Abstract
A computer server receives from a mobile device, via a first network, a data structure request that includes a user identifier; associates a data structure with a user profile; and transmits the data structure to the mobile device. The user profile includes the user identifier and a current balance value. The server receives from a POS device, via a second network, a balance update request that includes an updated balance value, and a validation request that includes the user identifier and the data structure. The server determines that, prior to receiving the validation request, the server had associated the data structure with the user profile. The server replaces the current balance value in the user profile with the updated balance value; and transmits to the mobile device, via the first network, a balance update confirmation confirming that the server had updated the user profile with the updated balance value.
