SAP Customer Checkout in Handheld device

Hi,

Can SAP Customer Checkout be installed and used in handheld devices which can be used for taking the customer orders ? We know that to install SAP Customer Checkout the operating system should be windows based and to install in Tablets its recommended to use Microsoft Surface Tablets but what about handheld devices ?

If it can be installed in handheld devices can you please recommend the name of such handheld devices ?
