Direct Answer
Choose your QR code type based on what you want to happen when someone scans it. URL QR code: opens a website, menu, listing, or online platform (most common — 85% of QR codes). WiFi QR code: automatically connects the phone to a WiFi network — for restaurants, hotels, offices. vCard QR code: saves contact details (name, phone, email, company) directly to the phone's address book — for business cards, networking. Text QR code: displays a plain text message on screen without internet — for product labels, instructions, promo codes.
The four types cover every real-world use case. URL is the default for linking to anything online — menu pages, Google Business profiles, social media, Shopify stores. WiFi removes the friction of password sharing in any guest-facing environment. vCard replaces paper business cards with a single scan that saves all contact details. Text works offline without any internet connection, making it ideal for industrial labeling, product packaging with static information, and environments with poor connectivity. All four types are free at UnlimitedQRCodes.com with no account required.
Use text when: (1) there is no internet connection at the scanning location, (2) the content is static and doesn't need to update (serial numbers, batch codes, promo codes), or (3) you want the information to display directly on screen without opening a browser.
No — a QR code encodes one item. For multiple purposes (e.g., menu link + WiFi credentials), generate separate QR codes and display them together. Many restaurants display three QR codes: menu, WiFi, and Google reviews.
