Free QR Code Generators for Business: WiFi, vCard and Contactless Signs

You don't need a paid subscription to generate a QR code for WiFi, a vCard, or any business sign — free tools do the job just as well, and for a laser-engraved sign a static (non-changing) code is the right choice anyway. Here's how to generate one for each use case, and the mistakes that quietly undermine QR signs once they're made.

For a complete breakdown of every sign format, sizing and platform-specific review link instructions, see our complete wooden QR code signs guide.

What is a QR code and how does it work?

A QR code (Quick Response code) is a two-dimensional barcode that a smartphone camera can read. When a customer points their phone at it, it opens a URL, connects to a WiFi network, saves a contact, or triggers another action — instantly, without typing anything.

The key thing for signage: the QR code itself is just a link. The destination is what matters. Change the destination and you change what the code does — but if the code is laser-engraved into a wooden sign, the code itself is permanent. That means you need to think carefully about what URL you put in before you order.

Free tools to generate your QR code

WiFi QR codes

A WiFi QR code encodes your network name and password in a specific WiFi format (not a URL — this is a common mistake). Scanning it opens the phone WiFi connection prompt directly. Generate one free using our free WiFi QR code generator — no account, no subscription, no data collected. Enter your network name and password, download the QR code image, and you are done.

vCard QR codes

A vCard QR code saves your contact details directly to a phone — no business card, no typing. Useful for trade stands, networking events and name badges. Generate one free using our free vCard QR code generator.

Review, menu and social media QR codes

These are standard URL QR codes — you just need the correct destination link. For a Google review link, search your business on Google, click Get more reviews and copy the link. For a menu, use a stable URL you control. For social media, copy the profile URL from your browser.

Where QR codes work well on business signs

WiFi signs

A WiFi QR code sign is one of the highest-return investments a café, hotel or co-working space can make. Instead of printing a password card that guests squint at and mistype, a QR code connects them automatically. One scan, connected.

Google review signs

A QR code that links directly to your Google review page removes every step between a happy customer and a five-star review. No searching for your business name, no scrolling, no friction.

Digital menus

A QR code on a table sign linking to a PDF menu or online ordering system was the workaround that became the standard. Even businesses that have reverted to printed menus often keep a QR code sign on the table for allergen information or the full drinks list.

The URL here needs to be stable — if your menu PDF URL changes every time you update it, the old signs become useless. Use a permalink or a short link you control.

Social media follow signs

A QR code linking to your Instagram or Facebook profile at the point of sale or on the counter turns footfall into followers. Works well for food businesses, salons and independent retailers where customers have a moment of dwell time.

Contactless payment signs

Card-only and cashless payment signs with a QR code linking to a payment link or app download are increasingly common in hospitality. A clear sign at the counter avoids the awkward conversation when a customer tries to pay with cash.

vCard and contact signs

For trade stands, networking events or client-facing environments, a QR code that saves your contact details directly to a phone means no business cards, no typing. Use it on a name badge, desk sign or promotional keyring.

Common mistakes with QR code signs

Linking to a homepage instead of the specific destination. If you want a review, link to the review page. If you want a menu download, link to the PDF. Every extra click between the scan and the goal loses a percentage of people.

Using a dynamic QR code service that charges a subscription. Most QR code generators are free for static codes — a code that encodes a fixed URL. You only need a paid dynamic service if you want to change the destination after printing. For a laser-engraved sign, a static code is the right choice anyway, because the sign itself is permanent.

Not testing before ordering. Generate the QR code, scan it on your own phone and on a colleague phone before you send it to us. A code that works on one device and not another usually means the URL has an error or the format is wrong.

Making the code too small. QR codes need a minimum size to scan reliably — our technical guide to QR sizing on wood covers exactly how small is too small.

What format should the QR code be?

For wooden signs, we generate the QR code from your supplied URL or WiFi details when you order. You do not need to supply an image file — just the destination. For WiFi signs, supply the network name (SSID) and password. For URL-based signs, supply the full URL including https.

Which QR code sign should I order?

Frequently asked questions

Can I change the QR code destination after the sign is made?
No — the code is laser-engraved and permanent. If you think the destination URL might change, use a URL shortener or redirect you control, so the sign URL stays constant even if the underlying page changes.

Do I supply the QR code image or do you generate it?
We generate it from your URL or WiFi details. You do not need to produce an image file. Just supply the destination in the personalisation box.

Will the QR code work on all phones?
Yes — QR codes are readable by the built-in camera app on all current iOS and Android devices. No separate app needed.

Can I have a QR code on a name badge?
Yes — our QR code name badges are engraved with a personal QR code linking to a LinkedIn profile, website or vCard alongside the wearer name and job title.
