This is how a lot of transit cards work, unfortunately.
Most of those (used to) work offline too, as long as there was money on the card. Not something an online payment system or app needs to deal with.
if i recall, in singapore, the transit card costs are refundable.
I think that's the only place i've seen it refundable.
