2 в 1 , кредитные карты становятся умнее.

Одна карта, но несколько банковских аккаунтов

Новые кредитки позволяют добавить необычные функции в привычный нам пластик , а именн : нескоько аккаунтов и все благодаря  RFID технологии


A pair of new computerized credit cards can re-program their own magnetic stripes and hide their account numbers, providing added security for bank customers who don’t want to carry lots of plastic inside RFID-proof metal wallets.
The "MultiAccount" card, which debuted at this week’s DEMO conference, looks just like a normal card, but with buttons on its face in the place of that holographic eagle seen on VISAs. Users can push a button to switch between cards, and an indicator light will let you know which account you’re using — such as a business account or personal account.
Как это будет здорово , нажал кнопочку или набрал ПИН и переключился между карточками.
Но есь и реальная опасность такой технологии , что будет если у вас ее украдут? Украдут все разом.

Помню была у меня мулти сим карта в телефоне, и потом у меня украли телефон, вот был гемор по востановлению 4 номеров, двух моих сосбственных и 2 корпоративных , а жулики целых 3 дня по ним звонили. За 3 дня мой телефон тогда доехал до Украины и потерялся в Крыму....

The “Hidden” card has five buttons and a tiny display that obscures part of the credit card number. Users have to enter a PIN to uncover the whole number and unlock the magnetic stripe, according to Technology Review. After a period of time, the numbers disappear again and the magnetic stripe is deactivated, so it would be worthless to a thief who lacks the right PIN. The cards have a lithium-polymer battery and are fully waterproof, a nice feature for those who leave their cards inside jean pockets, sending them through the washing machine.
Card-maker Dynamics Inc. dubbed the technology “Card 2.0,” noting that magnetic stripe credit cards date from the 1970s. But as Gizmag points out, it’s far from the first future-y credit card to offer new consumer protections — few of which have really caught on.
Still, we particularly like the idea of one card for multiple accounts, reducing the fat-wallet Costanza effect.
