Vodafone Fiji has sold 17,000 e-ticketing cards in the Central and Eastern divisions as of Saturday last week.
Head of corporate affairs Shailendra Prasad said they would be selling cards in the Northern Division next week with sales in the Western Division starting this week.
Mr Prasad said there had been cases where passengers were not being allowed to use the cards.
However, he confirmed that there was no problem with the e-ticketing machines or the cards.
"Vodafone has delivered to the specifications required by the Land Transport Authority and the system is working as per requirement," he said.
"The challenge has been more so on part of the drivers and some companies."
Mr Prasad said except for Shore and Tebara buses, all other bus companies were using the e-ticketing services.
"They have some issues with the system which they have raised with LTA," he said.
The e-ticketing cards are sold at two dollars and will increase to $10 after three months.
Mr Prasad said the cards cost $17 and Vodafone was subsidising $15 at the moment.
"After three months, the company will be subsiding $7," he said.
