South Africa's Department of Social Development has seen a dramatic fall in fraud thanks to the introduction of biometric identification, according to a senior official.Social Development Minister Bathabile Dlamini said on Monday that the fraud cases registered with the department has fallen from 3,571 in 2013/14 to 1,072 in the past financial year.The department has also revealed some 149 million rand (US$12.3 million) in social grant fraud since biometrics were introduced in 2012, although it has recouped just 2.3 million rand of this.In 2012, South Africa launched a re-registration of all beneficiaries in 2012 and introduced biometrics such as fingerprints and facial data on the South African Social Security Agency card.The department now also aims to introduce biometrics for its staff, and an inspectorate to further root out grant fraud.
