Certified scales

You can attach a scale to your Toast POS device to sell menu items by weight. For example, a restaurant might sell ice cream by the ounce and lobster by the pound. When the weighed menu item is ordered by a guest, the item is placed on the scale and its weight is automatically detected by the Toast POS system. The system also automatically prices the item on the order screen.

The Toast POS system supports the Brecknell 6710U and 6720U scales. You can attach either scale to a Toast POS device through a USB port. Both scales work only with a USB 2.0 cable (which Toast provides).


National Type Evaluation Program (NTEP) Certificate # 18-111 certifies that the TOAST POS with Brecknell Scale meets the requirements of the NIST, Handbook 44: Specifications, Tolerances and Other Technical Requirements for Weighing and Measuring Devices, 2018, as adopted by the 102nd National Conference on Weights and Measures (NCWM).

Before you can use an integrated scale on your Toast POS devices, your restaurant must be enabled to display the weighed items configuration and to validate the configured units of measure. If your restaurant has not been enabled for scale certification use, contact Toast support.

After your restaurant has been enabled for scale certification use, no further configuration on the Toast administration back-end is required for the Toast POS system to interface with the scale. You must, however, configure menus and menu items for tare weight and unit of measure, as explained in Configuring Tare Weights and Units of Measure.

When using a scale, keep the following in mind:

  • Before using a scale, check your state and local government regulations that govern the use of scales and the sale of weighed food items to make sure your restaurant is in compliance.

  • You cannot enter weights manually into the Toast POS app. Only automatic weighing is supported.

  • When you weigh a menu item, the unit of measure configured for the menu item must match the unit of measure configured for the scale. For more information, see Changing the Scale Unit of Measure.

  • You can void and then re-weigh a menu item.

  • The NTEP CC (Certificate of Conformance) number is displayed on the Device Setup screen of a Toast POS device. This number cannot be changed by the restaurant.

The following sections provide information on the use and configuration of scales in a Toast restaurant.
