There are three people in the image. The person on the left is wearing a blue shirt and appears to be holding a white object with a barcode. The person in the middle is dressed in a white shirt and is also holding a similar white object with a barcode. The person on the right is wearing a black shirt and is holding a white object with a barcode as well. All three individuals are standing close together, and their actions suggest they might be involved in some form of data collection or scanning process.
