How previews and digital manual delivery work
Understand what is visible before purchase and how the protected PDF delivery process works.
Every preview is a selection aid
Available previews are low-resolution, watermarked images of the first page. They are intended to help confirm the manual title, agency, model, revision, and other identifiers. A preview is not the complete publication.
The catalog listing describes the file
Each product page shows the classified brand, agency, model, document type, page count, file size, and detected SR codes when available. Use those facts with the preview before adding a manual to the cart.
Payment confirmation controls access
Checkout is hosted by Stripe. NFI Manuals does not store raw card numbers. A redirect from checkout does not unlock files by itself; the server waits for a verified Stripe notification before fulfilling the order.
Account and guest delivery
Signed-in customers can keep fulfilled purchases in their account. Guest customers receive a temporary order-access link at the address collected during checkout. Individual file downloads use short-lived, single-use tokens.
Protected originals are not public URLs
Complete PDFs are stored outside the public website path. Search engines and unauthenticated visitors can reach catalog pages and previews, but not the protected originals.
