US Patent 10445779 Boundary-specific electronic offers

In an approach to determining a boundary-specific offer, one or more computer processors determine a user of a mobile device is within a pre-defined physical boundary. The one or more computer processors determine a first notification of an offer corresponding to the pre-defined physical boundary. The one or more computer processors send the first notification of the offer to the mobile device. The one or more computer processors determine whether the user of the mobile device moved outside of the pre-defined physical boundary. In response to determining the user of the mobile device moved outside of the pre-defined physical boundary, the one or more computer processors invalidate the offer.
