During my tenure as Director of Engineering and Engineering Manager at MishiPay, we faced a pivotal strategic decision in late 2021. At the time, MishiPay had a strong commitment toward the "Scan, Pay, Leave" model via Progressive Web Applications (PWA) because it offered a frictionless "Bring Your Own Device" (BYOD) experience for both retailers and shoppers. While the social distancing requirements of the COVID-19 pandemic significantly boosted digital adoption , we realized that adoption alone wasn't enough. Shoppers typically enter a store with a specific purpose, and even aggressive in-store marketing often fails to distract them from their mission. We observed that because of deeply ingrained habits, shoppers only seek out a checkout solution once they have already decided to finish their journey—at which point they instinctively look for a physical counter. To meet shoppers where they were, MishiPay decided to build its own line of Self-Checkout Kiosks.
