NSW is at the centre of an unprecedented attack by an international criminal gang on retailers' EFTPOS machines, fleecing $50 million. The wave of attacks on EFTPOS machines was yesterday described by NSW fraud squad head Detective Superintendent Colin Dyson as "the biggest I've seen". Fast-food, convenience and specialist clothing stores are bearing the brunt of the crime. McDonald's is among the outlets whose EFTPOS machines have been targeted. People commonly swipe both credit and debit cards through the in-store machines to pay for goods and services at these outlets.
