How Static QR Code Generation Works

Quick Response (QR) codes are 2-dimensional matrix barcodes developed by Denso Wave in 1994. Unlike 1D barcodes that encode data across a single horizontal line, QR codes encode information both horizontally and vertically across a grid of black and white squares (called modules):

📐 Reed-Solomon Error Correction
QR codes embed mathematical redundancy through Reed-Solomon polynomial error correction. This enables smartphones to decode the information even if up to 30% of the QR code is scratched, dirtied, or obscured.
🔒 Static vs Dynamic Architecture
Many online generators create “dynamic” QR codes that redirect through a subscription server and break after 14 days. 4aey generates purely static QR codes where the actual payload is etched directly into the modules. They never expire and work forever without any recurring fee.
📶 Universal WiFi Schema
Our WiFi mode formats the payload using the international WIFI:T:WPA;S:MyNetwork;P:MyPassword;; protocol, allowing iOS and Android cameras to prompt “Join Network” in a single tap.

Frequently Asked Questions

Will these QR codes stop working after a few weeks?

No! 4aey generates 100% static QR codes. The website address, contact information, or WiFi credentials are encoded permanently inside the pixel grid pattern. As long as your destination website remains live, your QR code will scan successfully indefinitely.

What is the recommended QR code resolution for print?

For physical marketing collateral, business cards, flyers, and billboards, select the “Ultra-HD (1000 x 1000 px)” resolution option. This ensures crisp edges at 300 DPI without pixelation.

Are my WiFi passwords or contact information sent to your server?

No. The QR matrix calculation and HTML5 canvas rendering happen strictly inside your web browser’s RAM. Zero bytes are ever sent to our servers.
