QR Codes Can Save Lives

Those little black-and-white boxes are everywhere these days. QR (quick response) codes can be scanned with a smartphone or tablet, leading you to a website, providing contact information, launching an app, or sending a message. If your smartphone or tablet didn’t come with a QR code scanning app, you can download one for free in the app store. Then, you just open the app and scan a code, much like taking a photo. To create a QR code, you can use a free online generator like Jump Scan or SPARQCode.
