Contactless payments have become increasingly popular among US consumers since the COVID-19 pandemic, with a 30% spike in users between March and June 2020. Despite this growth, the US lags behind other mostly-cashless markets in contactless adoption. Retailers must now match consumer demand for tap-to-pay and mobile wallet payments to stay competitive. Over half of retail customers prefer contactless payments to avoid exposure to COVID-19, with 69% finding them more convenient than cash. To create safer and satisfying retail experiences, retailers should refashion kiosks and mobile point-of-sale (mPoS) systems to support contactless payments and self-service technologies. Android payment technology can accommodate everyone, including underbanked segments of the population, by incorporating peripheral hardware for cash-accepting devices. Retailers must deploy safe and self-serve kiosks and mPoS to retain customer loyalty in an uncertain marketplace.
