Time sensitive geo-location data for push notifications after shared transaction processing

A method comprising:

• in response to detecting a transaction processed by a first device through an online transaction processor platform, determining a first geo-location of the first device using a location detection component of the first device in communication with the online transaction processor platform;
• determining that the transaction is a shared transaction based at least on transaction data for the transaction, wherein the transaction data comprises a transaction time;
• determining a plurality of devices within a geo-fenced area associated with the first geo-location through a plurality of geo-locations for the plurality of devices, wherein the plurality of geo-locations are detected within the geo-fenced area during a time period associated with the transaction time;
• and
• pushing application data from the online transaction processor platform to the plurality of devices for an application of the online transaction processor platform on the plurality of devices, wherein the application data comprises an identifier for an account associated with the first device used to process the transaction.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• receiving transaction processing data for an electronic transaction processed by a first device of a first user, wherein the transaction processing data comprises a transaction time, a transaction amount, and a transaction location;
• determining that the first user processed the electronic transaction with at least one other user using at least the transaction amount;
• accessing geo-location data for a plurality of devices within a proximity range for the transaction location, wherein the geo-location data is accessed for a time period matching the transaction time;
• determining first contact data for the first user, wherein the first contact data comprises past data exchanges between the first user and a plurality of users;
• determining a second device for a second user associated with the electronic transaction processed by the first user using the geo-location data and the first contact data;
• and
• causing to be displayed, through an application executable by the second device, interface output data on the second device, wherein the interface output data comprises an executable process to provide at least a portion of the transaction amount to the first user.
