It appears users of Kangaroo cabs don’t need to worry about having enough cash in their wallets. At least, with a credit card they don’t need to worry about cash. Starting this month, users are able to pay taxi-fare using a credit card. The taxi driver will swipe the passenger’s credit card on a small gadget attached to his smart phone, the payment receipt will be sent as an SMS to the user’s phone (the person who is making the transaction will have to give the mobile number to the driver). The device is called MoMo.
