FAQ >> Publishing Codes

• Can I change the colors of an 2D code?
  
  Contrast is the most important factor when reading a code so we recommend that the colors remain black on white or vice versa. If you choose to change the colors, the number of phones that can read it may be diminished.
• Can I place a logo or other artwork over the 2D code?
  
  No. Placing anything on top of the code will prevent the code from being scanned. You should allow two pixels of space around the code. Download a user guide here.
• How do people know what to do when they see a 2D barcode?
  
  The 2D code and other 2D barcodes will eventually be a widely recognized symbol that signifies mobile content to the public. Until then you'll want to clearly communicate what the code does and how to get it. ScanLife offers the use and promotion of a shortcode which will help start the download process.

• Is the ScanLife application widely available in the US?
  
  ScanLife is the most widely available 2D barcode application. Millions of people can download it to their camera phone right now across all major carriers - and it's not limited to smart phones like Palm and Blackberry. Carriers like Sprint are also pre-loading the app on new phones, so you may already have it. Over 80% of new phones have a camera, so the numbers are growing very quickly.
• Are people charged for scanning 2D codes with their phone?
  
  ScanLife needs a data connection on the phone in order to execute an action from a 2D code. Standard data charges will apply to the user depending on their data plan, but the cost is minimal. To be more specific, each scan delivers about 250 bytes of data which would cost the user less than a penny if they do not have a data plan. After the 2D code has triggered an action, like opening a website, normal data costs will be incurred.
• What if I want to use my codes to promote my band or small business?
  
  We ask that all commercial-related codes be created under a Business Account. This account will give you many more options and there's no commitment when you sign up.
• Will the ScanLife data give me the user's name and phone number?
  
  ScanLife does not collect any personal identification information such as name, phone number or email address. All of this can be collected if the user "opts-in" after they scan a code. For example, an SMS code can initiate a text conversation or simply ask the user to enter their info on a web page.
