Well I'd strongly advise you to avoid AMEX card provided by Standard Chartered Bank (the only provider in Pakistan, I think) at all cost.
1. It is not accepted as widely as visa/master.
2. Standard Chartered Bank is worst when it comes to customer service. My statement date of AMEX card was 18th and believe me I'd receive statement on 19th which means next month I'd pay penalty. Every time they'd respond that my address is not correct which was not the case since all my foriegn and domestic mails are delivered at this address. I've serious compaints about their general banking too but I'd not discuss since its not the issue here.
3. Annual fee is 2,000 for basic cardholder.
I don't know if you have decided to go for this card or not but in case you're still deciding then I'd advise you to go for visa/master and avoid this. I've dealt with various banks and my personal experience suggests that Alfalah is best when it comes to credit cards. No fees nothing plus timely communication with very decent customer service.
