Treasure Hunts and Crosswords Built on QR Codes
Fifty scans an hour on a school network, sequencing that nobody can skip, surviving one missing code, and why a wrong clue is a page edit rather than a reprint.
Pairing a Device by Scanning a QR Code
A pairing code is a ticket, not a password. What the code carries in each of the three pairing shapes, why it has to expire, and the failures that follow a screenshot.
Where Your QR Code Scan History Actually Lives

Who Invented the QR Code, and Why Japan Got It First
Masahiro Hara, 1994, a Go board, and a survey of printed matter that produced the 1:1:3:1:1 finder ratio. Plus the part most histories skip: why Japan had a decade of ordinary use first.

A wearable code has to open a plain page with no app, no login and no signal. How to structure that page, why engraving still carries the critical text, and the public-versus-gated trade.
Direct Part Marking and Why It Is Usually Not a QR Code
Laser, dot peen and chemical etch make marks with no pigment at all. Why Data Matrix takes a fifth of the area, when QR still wins, and why the lamp decides everything.
GiroCode and the EPC Payment QR Format
What a GiroCode holds, the EPC069-12 line order, which banking apps read it, and why an IBAN printed into a symbol can never be corrected afterwards.
QR Codes for Photographers, From Album Cards to Client Galleries

Where the serial lives, why the printed string can never change afterwards, what a UUID costs you in module width, and which check digit catches a transposition.
Getting a QR Code Onto a Business Card That Still Scans
85 by 55mm leaves room for a 25mm footprint and not much else. Minimum size on card stock, bleed and safe margins, the finishes that kill a scan, and codes on coloured stock.

Scanning a QR Code on a Galaxy Phone Without Guessing
One UI ships five different scanners and keeps moving the switch for the main one. Photo mode, the Quick Settings tile, Bixby Vision's retirement, and why an iPhone reads the same code first.

French price display rules predate the smartphone and still bind. A code can carry allergen information by name, but it cannot be the price display a passer-by is entitled to read from the pavement.
Why Your QR Code Looks Too Dense
A dense code is a long string, not a rendering choice. What a tracking URL costs in modules, why level H adds more, and the 0.4mm floor that decides whether it prints.

The minimum separation between two codes measured in modules, why some readers take the nearest and others the first found, and the cases where one dynamic code beats two printed ones.
What You Are Actually Scanning When You Scan an Apple Pay QR Code
Apple Pay is NFC and has no QR payload. The three things people are really scanning, how iOS routes a payment URL to an app, and what a business should print instead.
The Page Behind a Code Is a French Website, Footer or Not
