AT&T is showing some clever thinking, leveraging its capabilities for managing micropayments via phone calling cards and using them to provide prepaid cards for purchasing online content. Their target outlets are convenience stores, and target market kids who would like to purchase gaming time, music and other entertainment. Parenthetically, it probably won't take long for the adult content marketplace to take advantage of this capability, also. But clearly this has a lot of potential for content purchasing in professional circles. Many corporate portals like to keep their individual users anonymous to outside content vendors, and a card mechanism like AT&T's offers the potential to offer these people ways to make on-demand content purchases that need not tip any specifics as to who is using professional content from outside sources. Securities analysts and traders especially may take note.
