Hi
I have a question relating to credit cards and paying abroad. I’m from the UK. I'm not sure if this belongs in the 'travel tech' section but couldn't think where else to put it.
I’m looking to stay at the ymca hostel in hong kong, and have emailed them as you can’t pay for their dorms online.
I have received a reply asking for my credit card details. Firstly, is it recommended to send your credit card details by email (i.e. in safety terms), and what needs to be included? (do you need to send the cvv number?).
Secondly, I’ve bought one flight ticket through airasia, and have a few more to get. I have paid through my RBS debit card, as I do not currently have a credit card. I’ve ordered one (the Halifax clarity one which doesn’t charge oversea fees) which should be here in a few days, but was wondering will I be charged extra by my bank for buying an airasia ticket over the internet, as they’re based in a different country.
Let me know if you need any more info, I’m finding it a bit confusing!
