What is the main conflict in The Bar Code Tattoo by Suzanne Weyn?

As the story opens, Kayla is in a meeting with her guidance counselor who has just informed her that she will not be receiving a scholarship to an art school as she'd hoped. Kayla is upset with the news but the disappointment is overshadowed by the fact that her family situation has become unstable ever since her parents accepted the bar code tattoos. Kayla encounters a group of students who are discussing their resistance to the bar code and becomes interested in their ideas. Over the coming weeks, she spends more time with the students and comes to have an active part in their group. The group makes plans to meet in the Adirondack Mountains if they are forced to leave their homes.
