Carpenter Realtors may be the first residential real estate brokerage in the Indianapolis area to use tag-reading technology for smart phones.

Specialized bar codes will be on Carpenter materials ranging from print advertisements to yard signs. When the phone snaps a picture of the bar code, the square footage, taxes and other information pops up on the screen. So does an offer to tour the property via video or photo gallery.

Senior Vice President Dave Caveness got the idea during a flight when a man in the next seat shot a picture of a bar code in a golf magazine and proceeded to watch a video of a golf lesson.

Caveness contacted Microsoft Corp. and became a test site for its Tag Reader software.
