It stands to reason that anything that has a value like cash, and which can be bought and sold, needs to be guarded as securely as cash. Examples are postage stamps, gift tokens and prepaid telecoms vouchers. At least in telecommunications the vouchers can be canceled when the theft is discovered, but if security is too weak to stop the theft, it may not be tough enough to discover it promptly either. Better to stop the initial theft than rely on blocking the cards later. Fortunately, Ghana Telecommunications were able to respond quickly enough to a recent robbery; read here about the theft of US$250,000 of prepaid vouchers from Ghana Telecommunications stores in Accra.
