Hacking attacks against sales terminals have risen by nearly a third last year, and the US is still leading the way in being insecure. Incidents affecting sales tills and payment systems increased to 31 per cent in 2016, according to research by security firm Trustwave, while incidents affecting e-commerce environments fell to 26 per cent from 38 per cent. Incidents involving sales registers were most common in the US, thanks to its tardy adoption of EMV chip technology and a reliance on chip and signature rather than chip and PIN payment.
