In 1986 Barclaycard was the first payment provider to introduce Process Data Quickly (PDQ) technology, which allowed in-store transactions to be processed faster and more securely than ever before. I joined Barclaycard in 1972 and was working in the Business Research team when we embarked on a huge project to transform how retailers take and consumer make payments.
Before PDQ technology was introduced retailers relied on “zip tap” technology, which involved taking an imprint or carbon copy of a customer’s card to create a voucher, which was sent to the appropriate bank to process. This system was not only admin heavy but also susceptible to human error and with ever increasing volumes desperately in need of modernising.
