BELBİM A.Ş - protecting essential payment services with zero-trust security

Istanbul is home to more than 15 million people and stretches over 594 square miles. Each day, citizens and visitors rely on İstanbulkart, a pre-paid multipurpose card, to pay their fares when using the city’s extensive public transport system. The card is now used for more than just travel—it’s integrated with COVID-19 safety measures from the Turkish Ministry of Health and with Mastercard advantages, and is accepted by thousands of food and drink retailers. For the public agency responsible for İstanbulkart, the pressure is on to provide reliable customer experiences, or risk bringing the city to a halt.
