For the cashless processing of payments at the annual Sziget Festival, one of the largest open‐air events in Europe, and a smaller festival at the lake Balaton, a combination of flexibility, quick application and feasibility was required. This was achieved thanks to the cooperation of specialized partners. Ingenico configured the 300 units of iCT220 payment terminals connected to TeliumPASS contactless readers in order to guarantee the acceptance of a prepaid contactless chip card at the festival site. Together with Metapay, these terminals were allocated to the retailers present at the festival. Metapay was responsible for managing the services on‐site, the logistics of over 30,000 cards that were handed out, from the distribution and topping‐up processes right through to the return of the cards. The processing of payments was carried out using the easycash Loyalty Solutions systems. Alongside the processed transactions, reports of blocked cards recorded by the Metapay staff at the festival (lost/stolen cards) are gathered centrally in the back‐end and then transmitted back to the terminals. The information gathered by all terminals over a certain period of time was regularly used to compile reports by Metapay, which also enabled the Metapay to ensure that merchants promptly receive their revenues. Ingenico Hungary was also responsible for the on‐site installation and the maintenance of the POS system. www.ingenico.de
