How Serve Legal can help
The Risk
Installing biometric systems such as facial recognition technology can improve operational efficiency, but it’s essential to ensure that the technology is serving its intended purpose. Without proper testing, businesses risk deploying systems that don’t meet their objectives or cause negative customer experiences.

How Serve Legal Help
Serve Legal’s In Situ Testing services provide a comprehensive review of your biometric systems in real-world environments. We test for accuracy, fairness, and user experience, assessing how the technology interacts with customers and staff. Our audits also offer benchmarks against competitors, ensuring that your systems are competitive and compliant with industry standards.
What sets Serve Legal apart is our scale. Our nationwide network of auditors means we can conduct In Situ Testing across various locations, ensuring that your systems are evaluated under different conditions and by a diverse set of customers. We also offer a coupled components approach, testing all relevant aspects of the technology, including age estimation, liveness detection, and fairness, to ensure comprehensive, end-to-end functionality.

About us
In early 2006, Ed Heaver and Julian Sargeson were alcohol retailers with a problem. The local authority had decided one of their sites was consistently serving underage people.
They wanted to check their staff, measure the site performance and demonstrate to the authority they were taking the issue seriously. They couldn't find a company providing a cost-effective service, so they decided to do it themselves.
The business has since grown to become the market leading provider of compliance auditing services in the UK & Ireland, and a leading voice in the conversations around age-verification, food allergy policy and the implementation of fair biometric testing.
