Abstract: In some aspects, the techniques described herein relate to a method including: receiving, at a machine learning engine and as input to the machine learning engine, a digital image file, wherein the digital image file includes an image of a transaction receipt; outputting, by the machine learning engine, text from the digital image file that is recognized by the machine learning engine, wherein the text recognized by the machine learning engine includes a transaction identifier, a transaction amount, and a tip amount; populating, by a point-of-sale device, a transaction finalizing form with the transaction amount and the tip amount; receiving, at the point-of-sale device and via the transaction finalizing form, a command to finalize a transaction associated with the transaction identifier; and initiating, by the point-of-sale device, an update command, wherein the update command updates a record of a datastore associated with the transaction identifier with the tip amount.
