The max any one Rabbit card can have stored on it is B4,000
While B4,000 is a small number relatively speaking, since there is no limit to the number of cards any one person can have or acquire, it could be one avenue used for illicit money movement… granted, for the big players - they’d probably not want to go this route, but perhaps for lower values, it could be…
To me, a B4,000 cap seems to be appropriate given the most expensive trip is around B60 (adult fare) one-way or B120 on a RT basis, and if traveled daily for 30 days, you’re now at B3,600.. so capping it at B4,000 seems reasonable in that light.
