You could ask if one of your local banks issues credit cards with low limits. Those are handy because you can't charge more than a certain amount to them.

I have a few friends in Pakistan, but I'm not quite sure how credit cards work there. I know it's against Islam to charge interest.

Credit cards are a tool. If you use them wisely, they will ultimately benefit you. But they can be dangerous and swallow you whole in a mountain of interest charges and account fees. Be careful.

I i can't say much about credit cards, but there are some gift cards for different credit card companies (For example, I use Visa Gift cards) that are viewed as credit cards and thus can be used online for however much money is placed on the gift card. It's how I was able to renew my premium membership last year.

Credit cards are an essential in this world because they give you a credit score which is needed for virtually  everything. All you do with a credit card is borrow money. You go online once a month and you give the money back. Or you pay it back in installments until it's paid off. This is normal pocket sized amounts of money to a couple hundred, maybe a grand at the most for most people.

 Interest is only accumulated when you are paying installments and are relatively small if your borrow amount is lower, to be honest even with high interest rates- I have a school bill of like 600.00 I'm paying off with my upcoming tax refund and I only get like $20.00 in interest if I'm not paying double or triple payments. That's an example. 

 If you pay the entire thing off by the end of the month or with in a short time, lets say like 3-6 month you don't accumulate it (or much of it). But it's good to because interest make the company money and it gives you a better score.  Of course in moderation. 

 You only put on it what you can realistically pay off. Example- using it for your groceries or gas and paying the money you had sitting in the bank on it or example my school bill because even with out my refund I could pay it off in 3 paychecks. 1 paycheck a month means it's gone in three months.

It's a necessary evil- and if you don't use it, you're not paying anything for it. except a one time a year fee which is like- retardedly cheap. They come in real handy in hard times (like when you live paycheck to paycheck or there's something you desperately need or a bill to pay but you can't at the moment and work when debit cards machines are down) . It's good to have one, maybe two tops.

I've MasterCard. It's handy and easy to use. And I've not had a single problem with it.
I only use it when no other option of payment is available.

They work fine if you have the money and pay the bills on time. Do they even charge interest in Pakistan? Isn't that against Islam?

If you are going to get a credit card, you might as well get one that gives you points or miles towards rewards.
