Credit recharge applications for telecommunications operators

A credit recharge web application was developed for one of the three telco companies operating in the Czech Republic. An idea to create a network of credit recharge places came in and similar applications were developed for different devices and systems – ATMs, betting terminals, etc. With an increase in popularity and usage of these applications, the rest of telco companies showed interest, so the applications are now used by all major telco players in the country.
