Weighing system and method for refillable containers

A computer-implemented method for weighing a product at a weighing apparatus, comprising:

• storing user data associated with a user, the user data comprising biometric data indicative of a biometric identifier of the user and container data indicative of an empty container weight;
• receiving a request to weigh a product in a container;
• receiving captured data indicative of the biometric identifier of the user from a biometric capture device associated with the weighing apparatus;
• outputting a control signal to control a scale associated with the weighing apparatus to weigh the product in the container;
• receiving, from the scale, weight data indicative of the weight measured by the scale;
• automatically identifying the container data associated with the user by comparing the captured data to the biometric data stored in the memory;
• and
• automatically determining a corrected weight of the product in dependence on the weight data and the container data that is automatically identified.

A computer readable storage medium including instructions to perform a method comprising:

• storing user data associated with a user, the user data comprising biometric data indicative of a biometric identifier of the user and container data indicative of an empty container weight;
• receiving a request to weigh a product in a container;
• receiving captured data indicative of the biometric identifier of the user from a biometric capture device associated with the weighing apparatus;
• outputting a control signal to control a scale associated with the weighing apparatus to weigh the product in the container;
• receiving, from the scale, weight data indicative of the weight measured by the scale;
• automatically identifying the container data associated with the user by comparing the captured data to the biometric data stored in the memory;
