The city’s neon green Rav-Kav electronic bus cards have been jinxed from the start. First there were the five-hour long lines at the Central Bus Station in November, when the first day of the Rav-Kav coincided with the return of university students to school, causing general mayhem and confusion. Now, a technological snafu between the Egged and CityPass ticketing systems has left thousands of people with cards that – oops – may not be useable on the train. There’s no way to figure it out until you try to swipe your card on a train and are denied, so good luck! The details are arcane: Anyone who bought a multiple-use card, or kartisia, before November 27 but uses it after January 1 can use it only on the bus, not on the trains. This despite the fact that the Rav-Kav cards were widely advertised to be usable for both. Sources at Egged give a long-winded explanation for the problem, which includes a mixup in the city code on the tickets.Despite the complicated explanation, the repercussions are clear: thousands of exorbitant fines for passengers who say they’re just trying to learn how to use the new system.David, an immigrant from Sweden, had a typical experience: after unsuccessfully swiping his Rav-Kav, which had the old code from November, he started to get off the train to buy a ticket, but the doors closed. An inspector then approached and asked for his ticket. David explained the issue, and the inspector asked for David’s ID. “Just to make sure the details match up,” the inspector told him. Then David was handed a NIS 186.60 fine.
