What can you actually use a QR code for?
A few of the most common, genuinely useful ways people use QR codes day to day — each one linked straight to the right tool.
Share your Wi-Fi without reading out the password
Print a QR code for your guest network and let visitors join by scanning it — no typing a long password on a TV remote keyboard or spelling it out loud.
Generate a Wi-Fi QR Code →Put your contact details on a digital business card
A vCard QR code lets someone add your name, phone, email, and company straight into their phone's contacts with one scan — no typo-prone manual entry.
Generate a Contact QR Code →Link a menu, portfolio, or landing page
Put a QR code on a table tent, flyer, or storefront window that opens a web page directly — a digital menu, an online booking page, a portfolio, anything with a URL.
Generate a URL QR Code →Invite people to an event
Encode the event name, location, and date/time directly into a QR code — scanning it offers to add the event straight to the recipient's calendar.
Generate an Event QR Code →Start a WhatsApp conversation
A QR code that opens a pre-filled WhatsApp chat with your business number — print it on packaging, receipts, or a storefront sign for instant customer support.
Generate a WhatsApp QR Code →Prove a product is genuine
None of the above can tell a customer whether what they scanned is real — that needs a code checked live against your actual product catalog. That's what Qrauthix's Simple and Secure QR tiers do.
