You push a button behind the credit card, it displays a unique security code which can be used as pin code for payment security. The battery in that credit card lasts for up to 2 years, it's the same size and weight as a normal credit card and it is unbreakable.
Why does the E-ink display 'turn off to save battery power'? Was that a mistake of the rep? E-ink shouldn't need power to retain its image.
