Buy your coffee with bitcoin: Real-world deployment of a bitcoin point of sale terminal
This work addresses the practical challenge of Bitcoin adoption for small businesses, though it is incremental as it builds on existing approaches.
The paper tackled the problem of enabling small businesses to accept Bitcoin payments for small-value transactions by designing and implementing a new Point of Sale system, Aunja PoS, which was deployed in a real-world cafe starting in October 2014.
In this paper we discuss existing approaches for Bitcoin payments, as suitable for a small business for small-value transactions. We develop an evaluation framework utilizing security, usability, deployability criteria,, examine several existing systems, tools. Following a requirements engineering approach, we designed, implemented a new Point of Sale (PoS) system that satisfies an optimal set of criteria within our evaluation framework. Our open source system, Aunja PoS, has been deployed in a real world cafe since October 2014.
