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.
