There are two fundamental categories of QR code — static and dynamic — and within them, multiple functional types based on what data they encode. Here is every type currently in common use, what it does, and when each one is the right choice.
URL QR Code
Encodes a website URL. The most common type. When scanned, opens the URL in the phone's browser. Right for: business cards, menus, packaging, signs, any application where a website link is the goal. Works as static (permanent URL) or dynamic (updateable URL).
vCard QR Code
Encodes contact information — name, phone, email, company, website, address. When scanned, prompts the phone to add a new contact directly. Right for: business cards, networking events, professional introductions. Significantly more useful than a URL code for pure contact exchange.
WiFi QR Code
Encodes WiFi network name, password, and security type. When scanned, connects the phone to the network automatically without the user typing a password. Right for: hotels, restaurants, offices, vacation rentals, any location where WiFi access is provided to visitors. Eliminates one of the most common customer questions entirely.
Phone Number QR Code
SMS QR Code
Encodes an sms: URL with a pre-written message and destination number. When scanned, opens the phone's messaging app with the number and message pre-filled. Right for: lead capture, appointment requests, and any application where a text response is preferred over a call.
Email QR Code
Encodes a mailto: URL with pre-filled recipient, subject, and body. When scanned, opens the email client with the message ready to send. Right for: feedback collection, inquiry initiation, and contact with a preferred email channel.
Payment QR Code
Encodes payment platform links — Venmo, Cash App, Zelle, Square, PayPal. When scanned, opens the payment app directly to the payment screen. Right for: small businesses, event vendors, service professionals, and any application where frictionless payment is the goal.
Calendar Event QR Code
Encodes a VCALENDAR entry with event name, date, time, and location. When scanned, prompts the phone to add the event to the calendar. Right for: event invitations, open houses, conference sessions, and any application where calendar addition is the goal.
App Store QR Code
Encodes an app store link for iOS or Android. When scanned, opens the app store directly to the app's download page. Right for: app promotion, loyalty program enrollment, any application where download is the conversion goal.
Geo Location QR Code
Encodes a geo: URL with latitude and longitude coordinates. When scanned, opens the maps app to the specified location. Right for: events, delivery locations, job sites, and any application where navigation is the goal.
The Type Every List Misses — Talking QR Code
Every type above is permanently silent. The scan completes. Something opens. The interaction is navigational.
The talking QR code at TalkingQRCodes.com is a URL QR code that opens a player page where an AI voice speaks immediately. It functions as any URL code does — plus it speaks. The restaurant table tent talks. The yard sign pitches. The business card introduces its owner. No other QR code type does this.
