Mobile app idea #37: QR Code Security

Updated: Feb 9, 2021

Have you found an unusual way to make millions?

Well, I've found one for you. You know how you need a badge or access card if you want to enter a workplace, school, or gated community? Often we would forget one or another and have to wait and tail someone in or run back home. It is such a hassle.

My idea is to develop an alternative but modern all-digital security system. This would involve an access point computer, cloud-based web service backend, and a mobile app in iOS and Android.

The mobile app would securely request a short-lived access code and generate a QR code on the screen along with the user profile photo. The user would simply show the screen to the camera at the access point to get access. The cloud service would be the brain of the system.

It is good for you because you don't have to carry an extra card in your pocket and worrying about forgetting it.

It is good for companies because it enhances security with two-factor authentication via facial recognition and unique short-lived QR code. It provides easy management and control. It also reduces costs from not having to purchase and issue plastic cards and microchips.

It's good for the environment because it eliminates plastic waste.
