Abstract: The disclosed productivity and management system for service-oriented businesses provides a system for person-to-person payment using facial recognition techniques and mobile device location techniques. Person-to-person payment includes tipping or other electronic transfer of funds from a payor to a payee. In some instances, the system provides a guest with a grid populated with face photos of nearby business staff and allows the guest to select from among the grid to determine a payee. The grid is populated with photos based on the proximity of the staff's mobile device relative to the guest's device, or a tip-receiving history of employees at a location near the user's device. The system allows the payee's personal identity, apart from the payee's appearance, to be not known to the payor, and not disclosed to the payor, to complete the payment transaction.
