Transaction verification program
What is it?
Transaction verification is a program of the Measurement Standards Division used to prevent consumer fraud and ensure fair competition by verifying that scales are properly functioning and scale users are correctly operating their scales. This program is carried out in a number of different ways, including screening packaged products for net contents compliance.

What does it accomplish?
  • It verifies that scales are in proper working order and are properly functioning.
  • It verifies that scale users are correctly operating their scales.
  • It ensures proper usage of scales when an inspector is not present.
  • It verifies the application of correct tare weights.
  • It protects consumers.
  • It maintains a level playing field.

What does it include?
Test purchases
When making test purchases of bulk food commodities such as coffee, peanut butter, honey, etc., an MSD inspector can verify the accuracy of a scale, the accuracy of the scale operator, and verify that a proper tare is programmed into the check stand computer. By making these small purchases it is possible to ensure that customers are getting what they pay for and are not being overcharged.

Method of sale
By ensuring that proper methods of sale are in place, an MSD inspector can ensure customers have the opportunity to make informed decisions on purchases. Fair competition is also maintained by requiring that all retail stores use the same method.

Packaged products screening
Screening packaged products involves check-weighing several packages for compliance with net contents statements. It provides a unique opportunity to examine a large number of items in a relatively short period of time. Conducting a screening gives an inspector the ability to observe any potential problems without unnecessarily destroying a large amount of product. From a screening, an inspector can determine which items should be further tested for net contents.

Packaged products testing
Packages that fail the screening may be given a full compliance test that meets the methodology provided in NIST Handbook 133. The purpose of a field test is to verify that the actual net contents of a package meet the net contents statements on the package. If a store is shorting its customers, it is not only hurting the customers, but it us also damaging to their competitors. Additionally, testing packages is another way to test the scales used in a store. Checking packages prepared by the meat department, for example, allows an inspector to verify the proper functioning of the scale used by the meat department as well as the correct usage by store employees.

Package labeling
Labeling regulations ensure that accurate and adequate information are provided on packages so that consumers can make price and quantity comparisons.

Transaction verification is a total system evaluation used to prevent consumer fraud and ensure fair competition.
