POS in Dynamics AX 2012 for Retail used Windows On-Screen keyboard.

I've seen this question asked in other forums so I'm posting the answer here in hope that it becomes discoverable. 

In Dynamics AX 2012 we removed the POS applications built in touch screen keyboard in favor of using Windows On-Screen keyboard.

 Here are two links for information about the Windows On-Screen keyboard. One for Windows 7 and One for POSReady 2009 (Windows XP is not supported for AX 2012.
