Scan&Go: Understanding Adoption and Design of Smartphone-based Self-checkout

: Since stationary self-checkout is widely introduced and well understood, previous research barely examined newer generations of smartphone-based Scan&Go. Especially from a design perspective, we know little about the factors contributing to the adoption of Scan&Go solutions and how design enables consumers to take full advantage of this development rather than being burdened with using complex and unenjoyable systems. To understand the inﬂuencing factors and the design from a consumer perspective, we conducted a mixed-methods study where we triangulated data of an online survey with 103 participants and a qualitative study with 20 participants. Based on the results, our study presents a reﬁned and nuanced understanding of technology as well as infrastructure-related factors that inﬂuence adoption. Moreover, we present several implications for designing and implementing of Scan&Go in retail environments.
