The first e-ticket system in Vilnius began operating in 2007. At that time, it was an extremely advanced system that changed the face of the city's PT - buses and trolleybuses had the first fully automatic composters that were able to "independently" transfer data to a unified system. The growing penetration of IT and the increasing needs of passengers, largely due to technological limitations, prevented the effective use of the existing system. The system was closed, inflexible, slow, unattractive to passengers, unreliable due to data loss, etc. The infrastructure of the service stations of the system used was also outdated. It was not possible to update it without installing a new system. Some parts of the then e-ticket system were out of production, any change in the operating process would have been very expensive. In addition, it was no longer possible to integrate emerging innovative payment solutions such as contactless bank card scanning or payments with mobile phones equipped with NFC technology into the existing system. Errors were sometimes found, and storing ticket information on the card created a risk of ticket counterfeiting activity.
