Clover System Currently only supports one weight scale (CAS SW-RS). This weight scale is bulky sits on the countertop and has max weight limit of 20lb. It is long overdue that Clover System developer add support for other weight scales.
Here are some examples:
1. Zebra MP7000 scanner scale
2. CAS LP-1000N
3. Datalogic Magellan 9300i/9400i Barcode Scanner

I am sure there are more frustrated clover users like me due to lack of other scale support.
