Greenline retailers get a loyalty card that lives in Apple Wallet or Google Wallet, points that accrue from the real Greenline ticket, and rewards that apply at checkout without a separate app. Greenline is a cannabis retail point of sale, or POS, built for Canadian dispensaries and covering inventory, sales and regulatory reporting. Sticky Cards subscribes to its event stream rather than polling on a timer, so an order, a refund or a loyalty update lands in Sticky Cards in real time.
A wallet pass is a real Apple Wallet or Google Wallet card, issued through Apple's PassKit and Google's loyalty card APIs, that installs from a web link with no app store download (Apple Developer, Wallet Passes, Google Wallet, loyalty cards). Wallet push is a notification sent to that pass over Apple and Google notification rails rather than through a mobile carrier, which means no per-message carrier fee.
The Canadian market is large enough for this to matter. Statistics Canada put seasonally adjusted sales at Canadian cannabis retailers at 506.8 million dollars in June 2026, from 501.3 million in May 2026, in the monthly retail trade release dated 21 August 2026 (Statistics Canada, Table 20-10-0056-02). That is a steady, mature market where the growth has to come from the customers a store already has. Retention is where the room is: Headset's retailer panel puts average cannabis brand retention at 34.0 percent of tracked category customers, with a median of 32.6 percent, as of July 2026 (Headset, Cannabis Brand Loyalty).
