Cashless payment is an often-discussed topic in Japan. To date, cashless payment is becoming the standard in most countries. However, Japan is lagging behind in terms of cashless settlements. The Japanese government is trying to raise the penetration rate of cashless settlements from the current 20 to 40% by 2025, showing subsidization policies. This study focuses on a QR code settlement system, which can be installed more easily with fewer costs than credit card systems. This study aims to clarify how much the introduction of QR code settlement affects small-to-medium-sized companies, where cash and credit card payments are mainstreams, in Japan. We perform a probability-based risk simulation to calculate how many benefits will be obtained if a small-sized Japanese pub restaurant introduces QR code payments. The simulation was carried out assuming 12 scenarios in total. Finally, it was found that the introduction of the QR code settlement would make the risk of running a pub restaurant lower, irrespective of business standing.
