In-person transaction processing system

A system comprising:

• one or more hardware processors;
• and
• a storage device storing instructions that, when executed by the one or more hardware processors, causes the one or more hardware processors to perform operations comprising:
• receiving, from a first user device, information regarding a service or an item;
• using the information, generating an unpublished listing;
• temporarily storing the unpublished listing in a datastore;
• generating a code associated with the unpublished listing;
• causing presentation of the code at the first user device, the code to be scanned by a second user device to access a transaction user interface associated with the unpublished listing;
• in response to receiving a request based on the code being scanned by the second user device, causing presentation of the transaction user interface on the second user device;
• receiving, from the second user device via the transaction user interface, an authorization for completing an in-person transaction;
• in response to receiving the authorization, completing the in-person transaction;
• and
• responsive to completing the in-person transaction, immediately deleting the unpublished listing from the datastore.

A machine-storage medium storing instructions that, when executed by one or more processors of a machine, cause the one or more processors to perform operations comprising:

• receiving, from a first user device, information regarding a service or an item;
• using the information, generating an unpublished listing;
• temporarily storing the unpublished listing in a datastore;
• generating a code associated with the unpublished listing;
• causing presentation of the code at the first user device, the code to be scanned by a second user device to access a transaction user interface associated with the unpublished listing;
• in response to receiving a request based on the code being scanned by the second user device, causing presentation of the transaction user interface on the second user device;
• receiving, from the second user device via the transaction user interface, an authorization for completing an in-person transaction;
• in response to receiving the authorization, completing the in-person transaction;
• and
• responsive to completing the in-person transaction, immediately deleting the unpublished listing from the datastore.
