Another problem with prepaid credit cards is that they represent opportunities for abuse of merchants. Many people complain that when making purchases in restaurants or stores, merchants take more money than they need. This cannot happen with cash, because when you pay in cash, merchants do not have access to your account. The best way to avoid this is to pay a credit card only in authoritative stores and immediately check your balance after transactions. Sometimes errors happen, and it is important immediately, as soon as possible, to identify them.
