Bearhouse writes "From the BBC:
A credit card with an LCD display and built-in keyboard has been launched in Singapore by Mastercard.
The card has touch-sensitive buttons and the ability to create a "one-time password" — doing away with the need for a separate device sometimes needed to log in to online banking.
"We brainstormed on ways to make it convenient and yet secure for customers," said V Subba from Standard Chartered Bank, which is collaborating with Mastercard.
"The question was: instead of sending customers another bulky token, could we replace something which already exists in the customer's wallet?"
Sounds convenient but perhaps less secure than having a separate device...I also wonder how robust it will be?"
