Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.

When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.

Application does not show up in Android Market for Motorola XOOM tablet - Stack Overflow - 0 views

I had the same issue. Along with including android:xlargeScreens="true" I found this to be the fix.

The Android Market treats as though requesting a permission like CALL_PHONE also requests: <uses-feature android:name="android.hardware.telephony" /> The XOOM does not have telephony — the first Android Market-compliant device with that limitation. While it can have a data plan, it has no voice or SMS capability, and so it is treated as not having android.hardware.telephony. But, if you request permissions like CALL_PHONE, the Android Market by default will assume you need android.hardware.telephony. As a result, you will be filtered out of the Market for the XOOM. The solution is simple: for any hardware features that might be implied by permissions but that you do not absolutely need, manually add the appropriate element to your manifest with android:required="false": <uses-feature android:name="android.hardware.telephony" android:required="false" />
