Thank you all for your answers. Sorry I haven't replied sooner, I was at work till 10pm. After careful consideration and comparing exchange rates, transaction fees and bank charges for using our existing bank cards, we have decided on the Caxton FX. With regard to the security aspect, if we lose a prepaid card, the maximum that we could lose, is whatever we have loaded on the card. On the other had if we lose a credit card or debit card, we could stand to lose significantly more, as in all available funds on both. Thanks again for your answers.
