7 wacky products you missed at CES 2011

It's a good thing the glasses are designed to block out peripheral distractions. Otherwise, everyone in the room would be too busy admiring one another's slick 3D eyewear to pay attention to the action on the screen.

Marchon3D EX3D glasses will come out later this year and cost $30 to $35.

Citi ThankYou Prestige 2G credit card Credit card terms and rewards have become more and more complicated over the years, and the cards have followed suit. First, magnetic strips were added for electronic transactions. Then small chips showed up in some cards so that consumers could wave their plastic in the general direction of a reader to make a transaction, rather than having to swipe it.

A company called Dynamics has joined forces with Citi to create a new breed of credit card. The Citi ThankYou Prestige 2G Card is built on Dynamics' Card 2.0 platform, and it features two buttons on the front. By pressing the Regular Credit button, users can pay for a purchase with credit as they normally would. Alternatively, they can press the Request Rewards button, allowing them to redeem points or cash rewards when the card is swiped. (Pressing a button activates a corresponding light to confirm the selected option.)

This innovation will no doubt simplify reward-point and cash-reward redemptions -- so as long as the cardholder is keeping a running tab of his or her redemption points and cash rewards, as well as where they can be used and on what sort of purchases. Then again, the cardholder may press the Request Rewards button each time and hope for the best.

Dynamics Card 2.0 technology was named the Best of Innovations Winner for Personal Electronics award at CES, and it's pretty cool. Among the features available to banks and credit card companies for use in ther own cards are buttons for selecting which account -- say, checking or credit -- you want to access when swiping your card. Another feature requires a user to enter a PIN code to display the credit card number, making it less useful to thieves.

Reese's Peanut Butter Cups have gotten smaller. So they go together! Get it? Note: Feasting on too many handfuls of these nano-candies has an enlarging effect on the user's physique.
