Citibank credit cards are going to become more advanced next month, with their new high-tech makeover, according to The New York Times. Apparently, the new cards, named 2G, will have two buttons that let you choose how you want to pay for the purchase. One button allows you to pay with reward points while the other lets you pay with credit. The 2G cards will have little lights and a battery life of four years. Other types of electronic cards are popping up as well — one that will let you carry multiple accounts on a card and another that shows you part of your account number if you type in your pin. Do you think these new credit cards are a good idea, or are issuers just making things too complicated for users?
