Biometric cards to aid crackdown
The department plans to focus on notorious areas of welfare fraud, including casual trading, clothes recycling and the food industry.
A central part of the crackdown will be the introduction of Public Service Cards, a new card that will eventually replace existing social services cards.
The change promises to make it more difficult to commit fraud because the new card includes "biometric technology". This means that data including a person's photograph and signature is digitally stored.
