RFID-based cashless payment system / Mohammad Farid Saaid and Muhammad Naim Handani

Nowadays, most of the supermarkets or retail
organizations use the old-fashioned or conventional data
management and payment system. This current technology
would affect the productivity and face the consequences of this
lacking technology. Thus, some weaknesses such as data losses,
longer waiting time and many more will get involved in this
matter. Therefore, it is very crucial to propose a new intelligent
system with real-time and overcomes the limitations of the
conventional management system. Radio Frequency
Identification (RFID) technology is the most leading and suitable
to be proposed to overcome this limitation because it is wireless
technology, which using radio frequency as its method of data
transmission. Other than that, the Barcode technology will be
used as the way of tracking the product since a barcode system is
the cheapest way, and it has still been using widely in a retail
management system. Based on the study conducted, an RFIDbased Cash less invented to help the customer to make payment
without involving any cash but using RFID tag that contains
electronically cash yet it can increase the smoothness while
making payment. This system is developed with Graphical User
Interface (GUI) as user interfaces on the monitor to print out and
present the retrieved data information from a database that
developed with Microsoft Access, buzzer as the sound indicator
to show that the tag already scanned and green and red LED as
the light indicator to show the products are ready to be scanned.
During the development stage, the hardware, middleware and
programming integrated together for a complete system. After
that, some experimental test is conducted on investigate the
system capabilities such as detection capabilities towards
materials and the effect of tag position on tag detection distance.
In a nutshell, this cash fewer payment systems helped the
customers to make payment in a shorter period instead of the
conventional method.
