Quantum Application: A Smart Cashier-less Shopping Application with Biometric Payment Authentication

Retailing is an important business activity that enables consumers to buy products and services from different merchants. In 2018, 469024 establishments for wholesale and retail trade had been in the range of Malaysian retail firms. However, currently, Malaysia's retail sector remains in its comfort zone where the technology used in retail shops is obsolete and does not interact with consumers. A sample based on the questionnaire was used, and data from 30 respondents was obtained. The information was gathered and analyzed through a Google form. After testing and analyzing the result from the customer survey feedback form, the respondents agree that this project provides an interactive user interface and swift payment using biometric and interactive notifications for their in-store purchase. The biometric authentication payment is implemented by integrating payment gateway and Microsoft Azure into the server less functions with an accuracy of up to 93.33%. This research provides consumers with an interactive user interface, allowing customers to have biometric payment instead of cash and numerous e-wallet forms.
