What is an offline QR Code?

Anatomy of an offline QR Code

An offline QR Code has all the information encoded in the code itself and no Internet connection is necessary.

When you create an offline QR Code, you can pack all information in the QR Code itself. When you scan the QR Code your mobile device will be able to process the information offline for example creating an event or add a contact to your address book. There is no need for an internet connection, except when  you want to sync your event or contact into the cloud.

One big disadvantage of offline QR Codes is that once they are printed their content cannot be changed in comparison to dynamic QR Codes.

There are various standardized types of offline QR Codes explained below. You can create those types of QR Codes on your own by clicking on each of them or going straight to our free QR Code Generator.

Offline QR Code types

Text 

The simplest information you can encode in a QR Code is a text message containing up to 4.296 chars.

vCard

If you plan to print a QR Code on your business card you may want to use a vCard. A QR Code with a vCard encoded provides contact information that can be added to the phone's address book immediately after scanning.

Again: once your address changes you need to re-create the QR Code with updated address information. However, you can also create QR Codes with mobile business cards with dynamic vCards encoded.

Event

Thanks to this great standardization job, you can create a QR Code that contains the payment information in your invoices. Customers can pay using this functionality in your bank App (if available) only scanning the QR Code.
