Face detector is a good step to curb the touting prevalent at PRS counters. But there they may connive with the PRS counter clerk, and hand over their reservation slips before the clerk joins duty and also during tea break. For better results, the camera should keep an eye on computer screen/ clerk side of the counter as well.
