A subsidiary of France’s national train work SNCF, iDTGV was launched in 2014. The company offers a service which is 100% online, from reserving tickets to printing them. The company launched iDTGVMax in January 2015. The offer gives users unlimited travel on all iDTGV train journeys for one year for a set monthly tariff of €64,99. Anticipating the popularity of their offer, iDTGV looked for a payment solution to quickly onboard a large number of customers in a short period of time and to process recurring monthly payments.


The company required a payment solution to quickly and easily onboard a large number of customers in a short period of time, and to simply process recurring monthly payments.
