Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Smart Ordering Application for Assigning Sequence Numbers to Customers at Offline Sites

ABSTRACT: In this paper, we propose a new smart ordering application for assigning sequence numbers to customers. This system has advantages over existing ordering systems, for example, it does not require identifying information such as phone numbers or social network IDs, and could therefore protect customer data. In this system, inaudible high frequencies between 18 kHz and 22 kHz are used for communication between speaker and microphone. To evaluate performance, the system was tested across smart devices including the Galaxy S7 and S8, and iPhones 6, 7, and 8, and the results showed a success rate of 98.7%. The proposed system could be a useful service technology for offline sites that need to assign sequence numbers to customers because of high visitor rates.
