A photo of guests is taken by a brand ambassador at an event. We can supply the photographer for you, or if you already have promotional staff available then we just send you the camera and you do the rest. Once the photo is taken, the consumer is given a unique branded reference card (the size of a business card) which has a unique reference number on it. The barcode on the reference card is then scanned which links the photo to the consumer’s personal reference number on the card.
