The Star Micronics mG-S8200 Scale integrates via a wireless Bluetooth or wired USB connection with your Android tablet or Sunmi T2 Lite to automatically enter the weight of unit priced items into the Retail POS (S-Series) app as they are being sold. After setting up the scale hardware, connect the scale to a compatible register to begin using it to weigh unit priced items in Lightspeed Retail.
IMPORTANT: Laws regulating the use of scales in commercial transactions vary by state and region. Before using a scale to weigh and sell products, you must research and follow all local guidelines. For example, some US states require scales to be registered and set up by a licensed technician. Not obeying these rules may result in fines and legal action against your business.
