The detection system used to identify goods during checkout process in retail stores is using barcodes. This system utilizes barcodes that are already printed on the packaging to be scanned one by one. However, this system can still be improved in terms of the number of items that can be detected in one scan. In addition, there are products that do not have packaging and cannot be affixed with barcode labels. There is development potential that can be utilized, namely object recognition using computer vision. Besides being able to solve these problems, this method can reduce physical contact which is an added value in the conditions of the COVID- 19 pandemic. In the developed multi-object detection system, there is a user control block whose function is to receive input from the user and provide output according to the request. So that the system built can be used easily. This block consists of two main components, namely the Graphical User Interface or the system interface and Jetson Nano as the implementation site. To achieve the specified product specifications and characteristics, the user control block has several main features such as item counting, invoice printing, and inventory changes. Testing of this block is done by testing the features contained in the block and good results are obtained where all the features run well. In addition to the user control block, there are two other blocks. These three blocks are then combined into a single unit to produce a complete system. This system works according to the specifications determined based on both quantitative and qualitative tests.
