ScanLife needs a data connection on the phone in order to execute an action from an EZcode. Standard data charges will apply to the user depending on their data plan, but the cost is minimal.

After the EZcode has triggered an action, like opening a website, normal data costs will be incurred.

We ask that all commercial-related codes be created under a Business Account. This account will give you many more options and there’s no commitment when you sign up.

For example, an SMS code can initiate a text conversation or simply ask the user to enter their info on a web page.
