QR
Business Receipt Workflow
A simple counter-to-inbox workflow for small businesses: make the amount readable, turn it into a fresh QR receipt, scan it with a phone, and email the receipt on the spot to the customer and to the business's own receipt inbox.
1 · SCAN AND SELF-EMAILUse CREATE A READABLE TOTAL and QR TO PHONE. After scanning, the phone can use its normal email or sharing tools to send the receipt text to the customer and keep a copy for the business.
2 · AI RECEIPT ANALYSISLater, an AI assistant that has permission to access the receipt inbox can organize the emailed receipts, group dates and totals, summarize spending or sales, and prepare a clean analysis and report.
3 · RESEND ANY TAPE AMOUNTNeed another copy? Select a past entry from the CALCULATION TAPE to restore that amount or result, open CREATE A READABLE TOTAL again, and generate a fresh QR receipt for the customer or the business.
The QR is created locally by the Receipt Lab; it does not send email by itself. Email and sharing happen through the scanned phone's available apps. AI-generated bookkeeping or receipt reports should be checked against the original records before being used for accounting or tax purposes.
Runs entirely offline. Addition, subtraction, multiplication, division, integer powers, square roots and nth roots use arbitrary-length integer arithmetic. Up to 15,000 displayed decimal places is accepted; very large calculations can take substantial memory and time. Trigonometric and logarithmic functions use normal browser floating-point precision.

Receipt extraction or OCR can sometimes produce a continuous sequence of letters with missing word spaces. The companion String Separator Machine searches for likely word and phrase boundaries, shows the most likely and next-most-likely interpretations, and can export the results for comparison.
