a. via a Cape Town Pass sticker that has a unique QR code on it. The client clicks on the QR code with their bar-code reader on a smart phone. The QR code takes the client to the Cape Town Pass website where the free Cape Town Pass app can be downloaded. In the background Cape Town Pass knows from which sticker the client arrived at the website to download the app and thus when the client buys a pass, the system knows from which sticker the referral came. Each sticker is linked on our admin-backoffice to an Affiliate. When the client uses the pass (so that we know there will not be a refund request on the pass), the Affiliate receives the commission for that pass.
