The project has been successfully implemented thanks to a comprehensive effort of multiple teams from Payten Serbia, Turkey and Monri company, as well as several teams from Delhaize. The online card payment was enabled using the new method of integration, implemented by Payten for the first time - Client Side Encryption. CSE significantly improves user experience and the aesthetics of the web shop. Along with this innovation, the system also allows memorizing of buyer’s credit card data (CardOnFile) functionality, to make the shopping even more convenient for Delhaize’s customers. This integration contract is a large scale, complex project to last for several years, and as such is one more proof of Payten’s credibility in the region.
