eBay is upgrading the mobile apps for its various sites. There is a new Half.com for iPhone app that lets shoppers compare prices and sell products with barcode scanning functionality. Other enhancements let users pay for items with gift cards and coupons, share purchases on social networks and shop from other Apple devices.

AR to Try

eBay is also adding augmented reality to its mobile app that it launched five months ago for the iPhone 4, according to All Things Digital. A first for eBay, the new AR functionality gives users the choice to "See It On" as well as to build an outfit with "Outfit Builder."

With the former, iPhone 4 owners take a picture of themselves and then pinch and zoom to fit the glasses to their face. With the latter, a user designates favorite items of clothing for their "Personalized Closet." Then the app mixes and matches the pieces into outfits that can be saved or shared.
