QR codes by industry

Something the business already has online. Restaurants point codes at a menu or a review link, schools at a class resource or a form, and real estate agents at a listing's photos or a contact card. The code type depends on the setting: a static code for a fixed handout, a dynamic one for a sign meant to outlast whatever it points at now.

Usually not. Most industry uses point at a page a business already has online, a menu, a listing, a review link, guest WiFi, which only needs a free static code. A paid plan matters only for a hosted page built directly in the generator, or for a sign meant to be redirected to a new destination later without reprinting it.

Not necessarily. Every static code, for a menu, a syllabus link, WiFi or a listing, is made free with no account at all, so different departments can each generate their own without coordinating. An account matters only once dynamic codes are involved, since those are tied to whichever login created them and can be reassigned from that same account.

A separate code per location works better whenever tracking matters, since a dynamic code's scan count then shows which site is actually getting used. A single shared code is fine for something identical everywhere, like a corporate WiFi network or a general company page, where per-location numbers wouldn't change anything about how it's used.

Yes, for cases like a survey, a waiver or an attendance check, a code can link straight to a digital form so people fill it out on their own phone instead of on paper. It works best placed right where the action happens, a checkout counter or a front desk, rather than on a general flyer disconnected from that moment.

Sizing the code for a business card instead of the distance it will actually be read from is the most frequent failure at a storefront. A code meant to be scanned from a sidewalk or across a parking lot needs to be printed several inches or more across, not the roughly 2 cm minimum that works fine on a handheld card.
