Matching character strings with transaction data

A method, comprising:

• performing optical character recognition (OCR) on an image of a receipt to generate a first plurality of strings;
• retrieving a list of transactions, each transaction including a second plurality of strings;
• matching a first string in the first plurality of strings to a second string in the second plurality of strings;
• calculating a percentage of likelihood that the image of the receipt is associated with a transaction in the list of transactions based at least in part on a match between the first string and the second string, wherein the transaction in the list of transactions is associated with the second string;
• determining that the percentage of likelihood meets or exceeds a predefined threshold;
• in response to determining that the percentage of likelihood meets or exceeds a predefined threshold, rendering the transaction in the list of transactions on the display;
• receiving a user input that the transaction in the list of transactions is associated with the receipt;
• and
• causing the receipt to be stored in association with the transaction in response to receipt of the user input.

A non-transitory, computer-readable medium comprising machine-readable instructions that, when executed by a processor of a device that comprises a display, cause the device to at least:

• perform optical character recognition (OCR) on an image of a receipt to generate a first plurality of strings;
• retrieve a list of transactions, each transaction including a second plurality of strings;
• match a first string in the first plurality of strings to a second string in the second plurality of strings;
• calculate a percentage of likelihood that the image of the receipt is associated with a transaction in the list of transactions based at least in part on a match between the first string and the second string, wherein the transaction in the list of transactions is associated with the second string;
• determine that the percentage of likelihood meets or exceeds a predefined threshold;
• in response to a determination that the percentage of likelihood meets or exceeds a predefined threshold, render the transaction in the list of transactions on the display;
• receive a user input that the transaction in the list of transactions is associated with the receipt;
• and
• cause the receipt to be stored in association with the transaction in response to receipt of the user input.
