Types of customer tracking solutions
Visual Proof devices will capture your customer counts using a high-definition camera. The counts can be reviewed for accuracy and non-opportunities can be easily removed.
Infrared devices will scan your customers as they come through your entrance or walk around your store. They can usually removed employees by using an RFID tag, but they can´t accurately remove other non-opportunity counts. The accuracy of the counts can´t be verified.
These devices will ping your customer´s cellphone and can sometimes send personalized offers to them. However, they can´t track customers without cellphones, and the data can´t be verified. (check the trade regulations in your state before using this method)
