Problem it tries to solve
K. Eiamsaard et. al (2021) attempted to address the issue of theft in warehouse from authorized staff.

How it tries to solve
K. Eiamsaard et. al (2021) proposed usage of a system that consists of RGB camera that has three modules namely image capturing, face detection and face recognition.

Measurement
K. Eiamsaard et. al (2021) used standard evaluation metrics for face detection and recognition in evaluating the software.

Problem it tries to solve
K. Ananthi et. al (2021) tried to address the issue of difficulty in finding the product location in a warehouse.

How it tries to solve
K. Ananthi et. al (2021) recommended the usage of IoT based IoT inventory control system. RFID served as the IoT Component where data flow can be tracked using the reader device. In addition a web page is constructed for easy monitoring and communication.

Measurement
K. Ananthi et. al (2021) evaluates the system by looking at the cost aspect whereby he claimed that it consume lower costs than others.

Problem it tries to solve
R. Patil et. al (2017) highlighted the monotonous human labor nature of existing asset tracking system that can lead to error such as misplacement, lost or stolen where it can ultimately affect the hospital revenue and security.

How it tries to solve
R. Patil et. al (2017) introduced RFID based tracking consisting of RFID reader that is run by Microsoft Visual Studio and Microsoft SQL that act as the database.

Measurement
R. Patil et. al (2017) measures the arrival and outgoing timing of assets.

Literature Review with Respect to Inventory Tracking System using QR code for Electronic Warehouse

There are various works being conducted in refining Inventory tracking system. These works focuses on different problems to be addressed. R. Patil et. al (2017) highlighted the monotonous human labor nature of existing asset tracking system that can lead to error such as misplacement, lost or stolen where it can ultimately affect the hospital revenue and security. On the other hand K. Eiamsaard et. al (2021) attempted to address the issue of theft in warehouse from authorized staff. While R. Patil et. al is a bit more general, K. Eiamsaard is more specific on theft caused by authorized staffs. Another work is more concern about difficulty to locate any given item (K. Ananthi et. al, 2021). Locating an item is definitely an important aspect in tracking system. Like K. Ananthi et. al (2021) our proposed project also attempted to facilitate locating an asset in the warehouse while ensuring undesirable issues such as misuse and theft can be addressed.
In term of technology used in addressing the issue, R. Patil et. al (2017) and K. Ananthi et. al (2021) used IoT based system with both used RFID as the tracking device. K. Eiamsaard et. al (2021) on the other hand uses face recognition as detecting internal theft has been its main focus. Our proposed project will use QR code instead as QR code is widely used and does not required specialized equipment like in R. Patil et. al (2017) and K. Ananthi et. al (2021). Furthermore our work differs from K. Eiamsaard et. al (2021) as we did not focus on individuals, instead we focus on the goods. If the goods are misplaced the system will know and the person who is handling can be dealt with.
