QR Codes for Small Businesses: Menus, Wi-Fi, Payments and Links

A QR code is a small square pattern that a phone camera can read. Point the camera at it and the phone opens a web page, joins a Wi-Fi network, shows a phone number or saves a contact. For a small business, that means a printed poster, a shop window or a product box can connect people to your website or social page in about two seconds, without anyone typing an address.

They are cheap, they work on almost every modern phone, and you can make one for free. Here is how to use them well.

Where QR codes help most

Menus and price lists. A restaurant, salon or shop can link to a page or PDF with current prices. When a price changes, you update the page and the printed code stays the same.

Wi-Fi sharing. Instead of reading out a long password a dozen times a day, print a QR code for your guest network. Customers scan it and connect. The code holds the network name and password in a standard format that phones understand.

Social and review pages. Put a code on your counter or receipts that opens your Facebook page, WhatsApp chat or Google Business Profile review page. It makes it much easier for happy customers to follow you or leave a review.

Contact details. A code on a business card or flyer can save your phone number, email and address straight into someone's contacts.

Event and registration pages. Posters for a training, a class or a live session can link straight to the sign-up page.

Product information. Boxes and labels can point to instructions, warranty details or a how-to video.

How to make a good QR code

Check the address first. The code is only as good as the link inside it. Use a short, working address that you control, and open it yourself before printing anything.

Keep strong contrast. Dark code on a light background is the safest. Avoid light colours on dark backgrounds, low-contrast colour combinations and busy photos behind the code.

Leave a quiet border. Keep a clear margin around the code, about the width of four of its small squares, so cameras can find its edges.

Make it big enough. As a rough guide, about two to three centimetres is the smallest size for close scanning, and larger for posters people read from a distance. The farther away the scan, the bigger the code needs to be.

Do not stretch or crop it. Keep it square and complete.

Test before you print. Scan it with at least two different phones, in normal room light, from the distance people will use. Test the final printed version, not only the version on your screen.

Add a short label. A line such as "Scan for our menu" or "Scan to join our Wi-Fi" tells people what to expect and increases the number of scans.

Static and dynamic codes

A static code has the address built into the pattern. It never expires and costs nothing, but you cannot change where it points after printing. A dynamic code points to a short link on a service, and you can change the destination later. Dynamic codes are handy for campaigns, but many services charge for them and the code stops working if you stop paying. For something permanent, such as a menu, a good approach is to make a static code that points to a page on your own website, then update that page whenever things change.

Stay safe with QR codes

Criminals sometimes stick fake QR codes over real ones on posters, parking signs and payment stands, sending people to copycat pages. A few habits protect you and your customers.

Check that the code on your own signs has not been covered or replaced, especially in public places. Look at the address that your phone shows before you open it. Never enter passwords or card numbers on a page you reached through a code unless you are sure it is genuine. For payments, only use QR codes issued by your bank or mobile money provider, and never one that someone sends you in a chat message.

Make your own for free

The free QR code generator on this site, under Learn then Free tools, creates codes for links, text and Wi-Fi networks. It runs in your browser, so the information you type is not sent anywhere, and you can download the image to print.

One small code, placed in the right spot with a clear label, can quietly bring you more customers every day.
