Decentralized self-service checkouts

A system, comprising:

• a distributed transaction scanner;
• a distributed transaction scale;
• a distributed payment station;
• wireless beacons;
• and
• a server, comprising:
• a processor and a non-transitory computer-readable storage medium;
• and
• the non-transitory computer-readable storage medium comprising executable instructions that when executed by the processor cause the processor to perform operations comprising:
• detecting a device of a shopper entering a store using at least one of the wireless beacons;
• generating a transaction identifier for a transaction associated with the shopper within the store;
• linking the transaction identifier to a device identifier associated with the device of the shopper;
• triangulating wireless signals of the device with second wireless signals of the wireless beacons to maintain a current location of the shopper within the store;
• reporting, in real time, the current location to the server;
• transmitting, by the distributed transaction scanner, a ping to the device of the shopper to receive the device identifier and the transaction identifier from the device of the shopper before the distributed transaction scanner reports item information to the server;
• adding first item codes that were scanned by the distributed transaction scanner and that were associated with first items to the transaction based on the current location of the shopper and a known location of the distributed transaction scanner;
• adding second item codes and item weights that were weighed by the distributed transaction scale and that are associated with second items to the transaction based on the current location of the shopper and a second known location of the distributed transaction scale;
• synchronizing updated item details for the transaction with a mobile application of the device of the shopper;
• processing, by the distributed payment station, a payment for the transaction on the current location of the shopper and a third known location of the distributed payment station;
• and
• maintaining a transaction log associated with the shopper, the transaction log including the metrics indicative of a path of the shopper through the store and types of items scanned or weighed by the shopper;
• wherein the distributed transaction scanner, distributed transaction scale, and distributed payment station are networked together via a communicative coupling to the server and are modular and reconfigurable within the store and are networked together via a communicative coupling to the server.
