Practical ways a shop, cafe or service business can use QR codes for menus, reviews, WhatsApp, WiFi and contact cards, plus printing tips and how to avoid QR code scams.
A QR code is one of the cheapest ways for a small business to connect a physical place with something online. A customer points a phone camera at it and lands on your menu, your map pin, your WhatsApp chat or your review page, with no app and no typing. This guide offers practical ideas, tells you how to print codes that scan every time, and covers the safety side that most guides skip.
Link to a page or a PDF with your menu. Keep the file small so it loads on a slow connection; see how to make a PDF smaller. A short note beside the code, such as “Scan for our menu”, helps people who have never used one.
Ask for feedback right where the customer is happy: at the till, on the receipt or on the table. Link directly to your review page so it takes one tap.
Many customers prefer to message. A WhatsApp link has the form https://wa.me/ followed by your number in international format, digits only, with no plus sign, spaces or leading zeros. Put that link in a “Link or plain text” code. Test it with another phone.
The WiFi type holds the network name, security type and password, so guests can join from the camera app. Remember that the code contains the password: display it only where you are happy for people to see it, and consider using a separate guest network.
The contact card type (vCard) stores your name, company, phone, email and website. It suits business cards and counter displays. Keep it short, because every extra field makes the code denser and harder to scan.
Link to a map pin or to your booking form on shop windows, delivery boxes and flyers. People passing by can get directions or reserve a slot at any hour.
For a poster or a van, a phone code lets a person call with one tap, and an email code opens a message with the address and subject already filled in.
You can create all of these with the free QR Code Generator, which runs in your browser, so a WiFi password or a contact card is not uploaded. A step-by-step is in how to make a QR code.
A static code stores the address directly. It never expires and nothing is tracked, but you cannot change the destination after printing. The sensible way to plan is to point it at an address that you control and can keep stable, for example a page on your own domain, a profile link or a short page where you keep the current menu. If you ever need to point elsewhere, you update that page and the printed code keeps working.
Because people cannot read a QR code with their eyes, criminals use that. Typical tricks are a fake sticker placed over a real code on a parking meter, a poster or a restaurant table, or a code that leads to a page imitating a bank or a payment screen. Some practical steps for a business:
And for customers, a few good habits: look at the address your phone shows before you tap it, be careful with codes in public places that look stuck on, and do not enter passwords or card numbers on a page you reached from a code you do not trust.
Use QR codes where a customer is already standing or looking, link to something you control, print them big with strong contrast, test with several phones and check them regularly. A code that is well made and well maintained works quietly for years.
Static codes, like those made on Docsworker, never expire, because the information is stored in the picture itself. The code only stops being useful if the page it points to disappears or changes address.
Not with a static code. To keep control, point the code to a page on your own website or profile, and update that page when needed, or print a new code.
A scam where a criminal pastes a fake code over a real one, or prints a code that leads to a look-alike page, hoping that people scan without checking. Businesses can reduce the risk by printing codes on the sign itself and checking them regularly.
At least about 2 cm (0.8 inch) for a code scanned from arm's length, and larger for anything people scan from a distance, such as a window or a poster.
