The American Express serve is a prepaid card, more like an ATM card because it has a card number and a chip and also, it's reloadable. Using this service was not quite funny from the beginning but I use it now at ease for online payment on goods purchased. I would have not been able to use it's services, all thanks to my uncle in Los Angeles who sends down money to me in Nigeria.
Moreover, the American Express card is usable in Nigeria which makes it interesting to me but it is not usable in the place I currently live, here in Lokoja. I learned that it can be used in ATM machines that accepts it but I have not found any here. Back then when I lived with my uncle, I used its card, American Express card, on MoneyPass ATMs and with no charges fees.
However, it has limits on different types of transactions but I don't always reach those limits because I don't always spend a lot. In conclusion, I really love the use of the American Express card because I receive money at ease from my friends and family members abroad.
