Many Touchatag applications are consumer focused, Haeger explained. Children coming home from school touch the tag to a reader on the home computer and a text message, e-mail or even a Tweet goes out to mom or dad to inform them their child has arrived home.
Tags can be used to open up a Skype connection. Tags can be attached to sides of a cube and, when touched to the reader, open a media player on the computer. Different sides of the cube represent the play, pause, stop and other functions of the player.
The company also has an online store of Touchatag applications.
But Touchatag was at JavaOne to promote enterprise uses of NFC, or "near-field communications," Haeger continued. "People were coming up to me and suggesting applications for it."
Touchatag could replace the big ring of keys security guards or janitors wear on their belts. A reader on each door they go through would record when they entered that room and when they left. A route driver could log when he delivered a new shipment of soft drinks to a particular supermarket.
Alcatel-Lucent announced during JavaOne that PingPing, an electronic payments service from Belgian wireless carrier Belgacom, would use Touchatag as the platform for helping developers create new applications for PingPing.
