Patent attributes
Tandem transactions facilitated through automatic application of a tandem transaction limit are provided. A system includes a group manager that identifies a group including respective identifications indicative of a first user and a second user. A transaction limit manager establishes a first transaction limit for the first user, a second transaction limit for the second user, and a third transaction limit for a combination of the first and second user. A transaction manager dynamically applies the third transaction limit based on a determination that the first and second user are performing a joint transaction. The transaction manager revokes the third transaction limit after a threshold time and applies the first transaction limit to first user transactions and the second transaction limit to second user transactions. Incentives are provided if a user remains at a location for a threshold amount of time or causes other users to visit the location.
