WHAT MAKES THIS DIFFERENT
A generator that tries to break its own work
This workflow does not stop at generation. It sends the exact generated bytes through an actual local decoder after five deterministic transformations, then binds the result and export bytes into a Receipt v1.
Generate a standards-shaped QR with a locked four-module quiet zone.
Model dots per module from final millimetres and printer DPI.
Decode original, downsampled, blurred, perspective-shifted and damaged variants.
Export SVG, PNG, CSV, JSON, Markdown, visual board and hash-backed receipt.
STATIC QR · NO EXPIRY SWITCH
A static QR code does not expire on its own
FastTool encodes your URL, text or WiFi details directly into a static QR. There is no FastTool redirect, account or subscription that can switch it off later. A URL QR can still stop working if the destination moves or goes offline; a WiFi QR stops matching when the network name, security type or password changes.
WiFi QR without an account
Choose WiFi, enter the network name and security details, and generate locally. The QR necessarily contains those details, so treat the exported file like the password it encodes and share it only with the intended audience.
SVG FOR PRINT
Use SVG as the scalable print master
SVG preserves the square QR modules as vector shapes when a designer or print shop resizes the artwork. PNG is useful for screen layouts and fixed-size documents. In either format, keep the white quiet zone clear and avoid stretching, cropping or placing graphics over the code.

HONEST METHOD
Digital preflight, not a physical guarantee
PASS proves only this deterministic digital test profile. It does not verify a printer, paper, ink, lamination, curvature, lighting, camera, scanner app or final placement. Always proof-print at the final size and test with multiple real devices.

The 4% perspective inset, blur, downsample and damage budgets are versioned FastTool simulation settings—not official DENSO or ISO tolerance limits. The evidence pack makes that boundary explicit.
