The personal records of PayMyTab customers have been left exposed online due to an unsecured Amazon data storage bucket. According to cybersecurity company vpnMentor, the database was brought to its attention via Helen Foster, a partner at Davis Wright Tremain, who shared the findings exclusively with TNW. PayMyTab — an at-table payment system — is a mobile app and device that enables diners to settle their checks using their secure EMV chip-enabled credit card.
