Business Week reports on NTT DoCoMo's plans to enable cell handsets to be used as credit cards.

After introducing handsets last year that double as debit cards -- allowing users to pay for small purchases such as soda or coffee from vending machines and convenience stores -- the company this year plans to make those phones full-fledged credit cards.

The Tennessean.com looks at Nashville-based Comdata and CEO Gary Krow.

Comdata was founded in Nashville 36 years ago and is a wholly owned subsidiary of Ceridian Corp. It has 1,200 employees and has expanded beyond the trucking industry, where it was well-known for its payment cards for fuel. It is a leading distributor of gift cards and has taken that product into other countries. And it also is the largest payroll card provider in the industry.
