[GNC] Accounting for a pre-paid electronic toll card

[Tony Vanson]

I'm hoping that someone on this list can aid my befuddled brain to get to
grips with my problem.
The tolling system here is not the automated ones I'm used to.
Here one needs to obtain an electronic card and, once done, must be charged
with a cash value prior to travelling and topped up with cash on a regular
basis.
My question is what category is this card and how do I treat additions and
subtractions from it?
I initially thought it might be treated as a credit card but the way it
operates it's obviously not.
Any advice would be much appreciated
