A digital receipt is an electronic proof of purchase, usually saved as an image, PDF, or exported record from a payment or expense system. It serves the same basic purpose as a paper receipt: to show what was bought, when, where, and for how much. In modern finance and security workflows, digital receipts are important evidence because they support reimbursement, auditing, and fraud review.
From a cybersecurity perspective, digital receipts matter because they are easy to copy, edit, and reuse. Attackers or dishonest users may alter amounts, change dates, or submit the same file multiple times across claims. Defenders look for metadata mismatches, duplicate files, OCR inconsistencies, and signs of image editing. Automated checks can help, but human review is still needed when a receipt does not match the surrounding transaction data.
