Security researchers at financial solutions provider NCR reportedly demonstrated how fraudsters could fool POS terminals into thinking chip cards are chipless by altering mag-stripe data contained on those cards. Some security and payments experts balk at the research, saying the demo only proves what we already knew. Experts say the demo’s findings are self-serving and misleading, since end-to-end encryption is a service NCR sells. In spite of EMV, what’s likely perpetrating so-called “fall-back” fraud is the debit and credit card numbers that were breached before EMV was widely deployed.”]
