I have not heard of any benefits to the user. If it helps the matatu owners, then what role does the government play in that? Why should government get involved in how manamba share cash with the owner? It will not stop robberies because they can still capture the matatu get all the wallets and mobiles and then demand and get passwords to that system and hack it for money. They can target the owner or whoever has the access to the cashless cash. So in terms of security I go with vooke, nothing to gain there for robbers. Only kuruti take on matatus. The graduates have bigger fish to fry.
Why should I not be free to pay cash? There is some illegality here. There is no place on earth where one lacks the option of paying cash. Of course private clubs. I did end up in one such club in Nairobi while trying to meet some Frenchman who lived nearby and was told I couldn't buy anything there for cash. So is matatu now a club?
If the idea is taxation, why not be open about it? This is the time government should be offering subsidies to lower the cost of transport. Farmers should have long ago been granted tax free fuel to be used on the farm in farm machinery.
