I love it when transportation companies race against each other to catch up with the latest technology and provide better services for its customers. After TransJakarta introduced the e-ticketing system, PT KAI Commuter Jabodetabek released its new e-tickets.
While there are many glitches in the new system, such as it being a single trip ticket (why PT KAI? WHY???), it's already a good sign that the company is switching to e-ticket (just think about those used paper tickets that people throw away).
Train is the means of transportation with the largest customers and they come from various background, from students to office workers to homemakers to the elderly. Therefore, the familiarization process faces more resistance and takes longer time than TransJakarta, whose main users are students and office workers.
I hope PT KAI will fix the problems soon, and who knows perhaps we can have one card that can be used for the train and TransJakarta in a not-so-distant future. Meanwhile, I need to find a bigger wallet to keep these cards.
