Any modern browser should work, and if you are experiencing trouble with the generator make sure you are running the latest version of your browser. We suggest Chrome or Firefox.

Log into our app with your scan.me account, and your scanning history should automatically sync with the website. You can review the info when you are logged in on your history page.

You can reset your password by clicking on the "reset your password?" link on the login page. You can also here.

If you're looking you to change your password, you can do it immediately on your account page.

The generator will crop and resize your image down to 200x200. Anything that size or larger will work great.

To scan a code with our app, you don't need to take a photo or press any buttons. Just make sure you're in the app and that the app is displaying the scanning screen (you should see a preview of what your camera sees). When you've located a QR Code or barcode to scan, move your phone (or tablet device) so that the code fits within the white square brackets. You may need to give your camera some time to focus and adjust for lighting, but once the code is detected, your phone will beep (and/or vibrate) and show you the content of the code.

Here are some things you can try in case scanning doesn't seem to work:

• Try scanning in better lighting (or turn on the light if your device has one)
• Make sure the code is not printed on a surface that is overly reflective, and make sure there is good contrast between the light and dark areas of the code
• Make sure the code isn't overly complex (meaning too many black & white blocks within the code)
• Make sure the code isn't partially covered, smeared, faded, or damaged
• Make sure the camera is able to focus clearly on the code (you want sharp edges on the code blocks). Note that your device may not have a camera that can auto-focus (if your device camera does not have auto-focus or the code is printed too small, you may be unable to scan certain codes since the app relies on image clarity to function properly).
• Try a variety of distances from the code for scanning (it doesn't necessarily need to fill the guide frame / square brackets - it can sometimes read better when appearing smaller on the screen)
• Make sure you are not trying to scan at an odd angle to the code (the code needs to appear completely square on the screen)
• If you're scanning a 1D barcode (with vertical lines instead of blocks), you may need to orient the camera so that the barcode is centered in the square brackets - the lines should still be vertical, but they should be perpendicular to an imaginary horizontal line across the middle of the square. In other words, if the code is more wide than tall (or has short lines), make sure the row of lines is the same distance from the top of the square as it is from the bottom.

Scan currently recognizes QR Codes and certain 1D barcodes (UPC, EAN, ISBN). Scan does NOT support Micro QR Codes, Data Matrix codes, or other types of 1D/2D barcodes.

The types of codes supported by Scan represent a vast majority of the codes intended for public use (many of the unsupported code types are used only for private, industrial purposes). By supporting the most popular code types, Scan is able to read codes much faster than other scanning apps, and adding support for more types of codes would only make the scanning experience slower / less reliable.

You may have successfully scanned something, but whether or not you see something useful depends on a number of factors:

• If the code is a website (as most are), you need to have a working internet connection on your device; otherwise, you may just see a blank screen as it tries to load. You may need to check your device and/or internet settings.
• Scan does not control (or ensure the reliability of) all scanned content. For this reason, you may experience loading issues due to errors, outages, or malformed content residing on systems that Scan does not control (for QR Codes, this is determined by the creator/publisher of the QR Code). You may need to contact the owner or administrator of the code creator/publisher.

If you would like to create your own QR Code content, we recommend using scan.me in order to provide useful, mobile-friendly content for yourself or your business.

No. Scan currently does not support scanning from a saved photo.

In Scan for iOS you can "swipe" left or right on a single history item to reveal a "Delete" button. Tapping on the "Delete" button will remove the corresponding entry from your history.
