More than one billion contactless transactions worth €12.6billion took place in Europe over the last 12 months – a three-fold increase when compared to the same period in 2014, according to Visa Europe. Britain is the country with the highest number of contactless transactions, with 52.6million worth more than €330million made in March alone, followed by Poland and Czech Republic, with 49.7million and 13.9million transactions respectively.
