QR Codes
From Artisans Asylum Wiki
Accessibility is everything! And providing information to guide tool access from a member's very first day in the shop can really help. QR codes are good access points.
Some shops make extensive use of QR codes for tools and procedures, particularly on tools that do not require tests to provide guidance, safety regulations, and tutorials for new users. Some shops do not use QR codes on tools that require tests in order to avoid diverting attention from the "tool testing required" sticker.
