From a customer:

The QR Code works best cause my presentation is a mobile app which is digital. Instead of me writing my contact information out on the pitch deck, the new way to pitch investors is having a QR - Code so after the meeting the investor can scan the code and have my information appear right there on their phone. Here is an example of how to do it in powerpoint.

In PowerPoint, go to the Insert tab, then click Get Add-In, and search “QR”. Find QR4Office and select it. Now, in your add-ins, you see QR4Office. The Microsoft Store has a ton of add-ins, and we have actually rounded up our favorite PowerPoint add-ins if you want to discover more!
