QR codes are becoming more and more popular, and you can find them in an increasing number of venues: magazines, bus stops, business cards, tv shows, stores. It is so simple to whip out your phone scan a code and get the information the creator of the code wanted you to have.

“Scan” is another entry into a fairly crowded, but enormously useful field. It’s simple, dependable, and has a few extra little features. In the screenshot below, you can see the main function screen. Open it, take aim at your code and it will run with it. Notice the tab at the upper left that says “Light?” If you’ve got the iPhone 4 or 4S, this will turn on your backlight if it’s too dark to get a decent image of your code.

At the bottom of the scan window are 3 tabs. The right-most tab has Settings. Just a few options here, the unique one is the ability to sign in to save your history. This can be quite handy. You also have the option of being able to directly to a website after scanning, or giving permission to go after seeing what website it is.

The first (final) tab shows the history of all the codes you’ve scanned. It also includes the date you scanned the code. I find having the date as important as having the url. Many times I remember when I found something, but not what it was.
