Now, a credit card that talks to you

London: Imagine your credit card talking to you and displaying your balance, while doubling as a reward card. Well, your imagination will soon turn into a reality.

Dynamics Inc is developing such cards- due to be introduced in the US later this year-which will have wafer- thin microprocessors and would run on batteries that can last up to three years.

However, the credit cards will only display personal information after a security code is entered.

Citibank has released the new 2G card, which has a programmable magnetic strip and buttons on the front for users to choose to use it as a credit card or just to spend reward points, the `Daily Mail` reported.

A trial is currently ongoing and, if successful, it could roll out across the country.

Even Mastercard has just released a card that has a small LCD screen which displays a one-time code which the customer can use to make an online purchase. It means even if someone`s credit card details are stolen, they will be useless to buy anything with without the one-off code.

Jeff Mullen, the CEO of Dynamics Inc which is working on several other high-tech cards, explained that the end of the magnetic strip has been mooted for years, but is still the dominant payment system in the world.

He said: "Magnetic stripe readers are being placed in more places than ever before like vending machines, movie theater kiosks and taxicabs.

"Even in Japan, where the infrastructure is in place and phones (which can make payments) have been distributed for seven years, the volume of phone payments is significantly less than one per cent share of transactions.

"European chip cards comprise only about 10 per cent of cards in world.
