In general, Windows Mobile and Windows Embedded Handheld devices cannot be converted to another operating system. You will need new to replace these units to run the Android platform.
However, Panatrack offers Honeywell CK75, CN75, CK75E scanners which can be converted from Windows Embedded Handheld 6.5 to Android. Honeywell will charge approximately $100 per device to convert to Android. Honeywell requires you to purchase a license for part number 454-087-001. Honeywell’s documentation states it is possible to revert to Windows Embedded Handheld 6.5 if desired. Please confirm all details with Honeywell before proceeding with the conversion.
