A computer-implemented method includes receiving reward points associated with a first account and a second account held by a consumer from a first issuer computer system and a second issuer computer system. A first conversion factor is applied to convert the reward points for the first account into reward money, and a second conversion factor is applied to converted the reward points for the second account into reward money. The first conversion factor is received from the first issuer computer system, and the second conversion factor is received from the second issuer computer system. The reward money from the first account and the second account are combined to provide aggregated reward money. The consumer is presented with options for using the combined reward points of the first and second accounts for making purchases, donating to charities, or sharing with other consumers from a single, integrated platform.
