The question of whether to use an “old”new” Visa card number has always been a mystery to many people, so it's good to know that new cards have a “vintage” look to them. That's not to say they look like old cards from the 1970s – in fact, they look like new cards from the current generation! Here's why:
First of all, if you're applying for a visa from abroad, the card issued is going to be unique, and so is the VISA back card. This is a standard procedure, even for non-immigrant cards, so you won't get a second chance at a new card. If you do get a second chance at a new card, there are many places to go to apply for one, and your old card may have a date on it indicating when it was issued.
Secondly, these cards are not like your typical credit cards. There is no security feature built into them, no expiration date, etc. This makes them a little easier to steal, but it also means that you don't need to worry about a person coming after your credit card information, as they're not going to have a credit card anyway. They can only claim the funds you used with that card, and that's it.
So why is a card so important? If you're applying for a credit card and you don't have one, it's really easy to lose track of where the money came from – especially if you didn't get a signature line on your application. It can take some time to recover if you don't have a signature, and sometimes this means waiting a long time to get approved for anything. If you don't have a signature, you can't get an automatic renewal, or even an upgraded card. You'll have to find another place to transfer your money from.
On the other hand, with a debit card, you can access your money without having to rely on your signature. You can transfer your funds from a bank account, and the bank will transfer it to your bank account right away. It's also very easy to withdraw funds, because there is no credit card number to worry about.
Finally, if you're trying to find a place to transfer your funds from, this card is very easy to use. There are many companies that allow you to use your card online, and send the money straight to any company. That's how it's best to go about transferring funds. If you're going to use your card for online shopping or to transfer money, though, make sure you only use your card on the merchant website that you want to use to make the purchase.
