A pump surrogate controller system and method allows multiple point of sale systems to control a particular service system. For example, a register at a cashier stand may activate the same fuel pump as an automated checkout kiosk. The surrogate controller may further coordinate the transmission of transaction data to the appropriate destinations. For example, transaction information relating to a fuel transaction may be delivered to the appropriate point of sale for completion. Transactions that are pre-authorized prior to a purchaser's arrival at a service station may also be activated using the surrogate controller. Fuel dispensing may be dependent on confirmation that the vehicle and dispensing pump are in close proximity.
