POS & Interface Scales

CAS commercial scales · Find your workflow

The right scale starts with what happens after weighing.

Send a weight to checkout, print a deli label, calculate a counter price or portion an ingredient. Choose the job first, then compare capacity, connections and the space on your counter.

Before you choose

  1. Do you need a printed label or a weight sent to POS?
  2. What is the heaviest item, including its container?
  3. Which exact register, software and cable will you use?

Check the complete setup

Capacity alone does not establish suitability. Confirm the resolution, usable platform size, power, label format and connection requirements for the exact configuration.

A USB or serial port does not prove compatibility with a SAM4S register. Send the register model, firmware version, scale model and cable details for verification.

Model listings describe available catalog configurations. Check each product page for current price and ordering options; confirm lead time for special-order items.

About this scale category

POS and interface scales for checkout systems that need weight data at the register. Compare compact CAS scales for grocery, produce, candy, specialty retail and other weighed-item workflows. Interface compatibility depends on the exact scale, cable, register or POS system, and software configuration, so verify the complete connection before ordering.

When to use a POS interface scale

  • Weighed items are priced in the register or POS rather than on the scale itself.
  • The checkout system needs a compatible serial or USB scale interface.
  • You want a compact scale at the checkout counter rather than a stand-alone price-computing scale.

For stores that need the scale itself to calculate price, see our price computing scales. For deli or grocery labeling, see label printing scales.
