Healthcare has the clearest use cases and the tightest constraints. The codes that work are the ones that move admin off paper without moving patient data into public view.
Make a QR code freeAppointment booking on a waiting-room poster, so patients rebook without joining the phone queue. Registration and intake forms scanned in reception, which cuts the clipboard entirely and produces legible data. Repeat prescription requests. Feedback forms on the way out, while the experience is fresh. Directions to the right department from the car park, which is a small thing that removes a large share of the queries at a hospital front desk. Every one of these replaces a phone call or a piece of paper with something the patient can do while they wait.
Never encode personal or clinical information into a QR code, and never point a public code at a page containing it. Printed codes are photographed, shared and left behind. Anything patient-specific must sit behind proper authentication, reached through a login, not through a scan. A code can take someone to the front door of a portal; it must never be the key. This is not a best practice, it is the line that separates a convenience from a data breach.
Codes on leaflets, discharge notes and posters linking to condition information, aftercare instructions, or a video demonstrating an exercise or a device. This works well because it solves a genuine problem: printed leaflets are expensive, quickly outdated, and available in only a couple of languages. A maintained web page can be updated the day guidance changes and translated far more cheaply. Keep the source authoritative and dated, and make sure the code is dynamic so a superseded page can be repointed rather than left in circulation.
A patient population includes people with low vision, limited dexterity, no smartphone and no data. Print codes large, place them at a reachable height rather than high on a wall, label them in plain words, and always provide the non-digital route alongside — a phone number, a paper form, a person. A code that becomes the only way to book an appointment excludes exactly the patients who need appointments most.

ReadSix rules that decide whether a QR code gets scanned: print size, contrast, quiet zone, error correction, a call to action, and testing on real phones.
ReadA static QR code can never be changed or measured. A dynamic one can be re-pointed after printing and tracks every scan. How to tell which your campaign needs.
