These parochial yet mandatory systems don't feel very futuristic to me. It's just a digital version of all prior pre-payment systems, with their tokens and cards. This isn't how you use widely available commonly understood technology to make things better.
Even the banks seem to know that - I can now get cash out of an ATM using only my smartphone and my banking app. They identified a problem, namely contactless payment is neither universal nor robust, and found a way to make things better by combining legacy systems with new technology to find a solution. In a hassle free way. No set-up required at all, and as quick and easy to use as anything else that involves the confluence of payment authority and a smartphone these days.
A nice little stop gap, until someone figures out how to do away with cash completely, which could be anywhere from 5 to 50 years away. If only buses were as nice to their customers as banks! Lol. (the point holds even if as I fear, the banks are only being this nice because central government told them to be nice)
