Microsoft Tags

A Microsoft tag is similar to a QR code. They are a 2D bar code that can be scanned using an application on a smart phone.

There is free reporting that lets you know how well a campaign is going. It uses engagement and ROI metrics.

To generate a tag you have to set up a Microsoft account.

Reasons to use tags are:

• They are free
• It connects print to web
• The design is more flexible than QR codes
• Free and easy to track
