How to use it

! Presets assume a typical receipt layout; unusually long receipts need the bands moved.
! The masked output is PNG, so file size grows compared with the original photo.

What is actually sensitive on a receipt?

Card last four digits, the invoice number, the tax ID (VAT), the store address and the order number, which together can identify a purchase.

Mask the card digits and keep the total, so the receipt stays usable for accounting.
