Some companies have thier own pilocies regarding using credit cards for online internet transactions. Some companies insist that you have to call them and ask them to open the card for transactions. This is a good feature for security purposes where nobody can use your card unnessarily online. But problem sometime occurs where you have to make an emergency purchase and you cannot contact the card provider to make the purchase. Other card provider also issue virtual card for online transaction. This is a cool feature whre you can replace the card anytime without affecting the card that you have in your wallet. The problem with this is some store insist on giving a proof of your card online by faxing them copy of the cards and here you will have a problem. Based on my experience, we have to have several cards with several features in order to tackle different circumstances with our online purchases.
