Scanning with a handheld scanner and the free PassVerifier app couldn't be easier. All you need to do is as the customer to show their loyalty pass and then scan this pass with PassVerifier. The scan is quick and then you enter the number of points you want to award in accordance with your own program.
A brief live capture of someone getting points because their loyalty card was scanned by a staff member who awarded them 45 points because of their purchase (this particular business awarded 10 points for each £1 spent).
Note that this video was made when the program was under the DrinkedIn brand. While the brand has changed to LoyaltyDog, the process is still the same.
