Please Press One (S05E06)

The Sliders arrive in a peaceful small town and see that a company named Data Universal seems to own everything. Maggie (Kari Wuhrer) tries to use a vending machine, but it doesn't take cash. Instead, an electronic voice asks for her data number. When she presses a button, a laser beam scans her. Suddenly a driverless van pulls up and she is propelled into it by the force of the laser. It speeds away as the others watch in disbelief. She finds herself trapped in a pristine white cell, a bar code bracelet strapped to her wrist. (iTunes)
