Is it safer to send credit card number via unsecured website form or by e-mail? What safer options are there?
Your biggest risk with a vendor like this is not that your Credit Card Number will be stolen in transit, it is that it will be stolen from the vendor. I agree with @mhoran that using a one-time number is the best plan, provided you have a bank that offers such numbers.  Bank of America calls it "Shop Safe" while Citibank calls it "Virtual Account Numbers".  I think Discover card has something similar, but less useful, in that they aren't really one-time use, and I think American Express discontinued their service.  AFAIK no one else offers anything like it.  If you can't get a one-time number, then I was going to suggest buying a Visa gift card, until I put together the fact that you are making a purchase in Asia and the gift cards are not authorized for international payments (due to PATRIOT act restrictions).  Visa does offer the V.me service which might help, but I doubt your vendor participates (or would even be allowed to participate) if they don't offer a secure order form.  You can open a pre-paid Visa card account, which is probably what I'd do. You can buy pre-paid Visa cards the same way you buy Visa gift cards, the difference being you have to register the pre-paid cards (thanks, PATRIOT act) before you can use them.  But it's not that big a deal to register one, you just fill out the online form your your SSN etc and you're good to go. Load it up with enough money to cover your purchase and the FX fees and then cut it up.
