It is best to track assets using automated techniques. Many technologies have matured and successfully demonstrated in many projects. These include, RFID (Radio Frequency Identification)Bar codes and QR codesBluetooth Low Energy (BLE)Wireless Barcodes are widely adopted due to low cost. A barcode is printed on paper or other material and pasted on objects that need to be tracked. A barcode contains a series of lines encoding the data which is read using a barcode scanner. This data (identifier) is usually mapped to records in a database which can be quickly retrieved by reading the barcode. QR codes are two-dimensional images serving similar function. Cameras scan the images, and the QR code software decodes the information contained in the images. QR codes can be printed easily without the need of expensive equipment.

The device layer contains the users’ devices, such as mobile devices, through which the construction labours onsite can react with the system. This layer serves two objectives: it provides access to sensed data from the sensing layer and enables the entry of data through the user interface (Akanmu and Anumba 2015). Mobile devices are portable/small-sized computing devices with a display screen for accessing and embedding information needed to coordinate between the office and the job site. Mobile devices have long been found useful in the construction industry for progress management (El-Omari and Moselhi 2011), managing punch lists (Menzel et al. 2008), safety applications (Wang 2008), and maintenance (Kim et al. 2009). Examples of mobile devices include personal data assistant (PDA), tablet PCs and smartphones. Using these mobile devices, the construction labourers can send their concerns or inquiries about specific components to the design team and gain fast feedback, and access virtual models, and update changes in a short time. Construction personnel can also easily embed information to be written to RFID tags before erecting and installing construction building parts. Some mobile devices have embedded barcode scanners and RFID, which can be used to scan and read the embedded information.

When camera was first introduced in phones, it was never expected to become a user data input source. However, in modern mobile devices, it has major roles to play such as high-definition image and video capture, video call, face recognition, and user authentication. Google's new visual search service allows users to take a photograph of a location and use it to perform a Google search. This service is intended to provide information on landmarks, businesses or associated locations, stores in those locations and products on store shelves, or in billboard advertisements in that location. Eventually, it could even identify people. Cameras can take snapshots of bar codes, and these bar codes can be read from the mobile screen using a barcode scanner. This idea has been used in one of the applications developed by Infosys to generate a paperless boarding pass for one of its client. Here, the user receives a soft copy of the boarding pass in the form of a 2D bar code. An agent at the airport scans the bar code directly from the mobile phone display screen and retrieves all the information about the passenger.

The QR code is a two-dimensional matrix code developed by Japan Denso corporation in September 1994 (ISO, IEC 18004, 2006). Since the QR codes can express Chinese characters efficiently, the QR codes have a good application prospect in China. In 2000, the national bureau of quality and technical supervision issued the national standard GB/T 18284–2000 for rapid response matrix codes. Currently, the QR codes are widely used in the field of automation management in the logistics industry of postal and telecommunication industry. In recent years, the popularity of smart phones has given rise to a new demand, the use of mobile phones as a barcode reading equipment, camera phones with 2D barcode reading software, can by means of the two dimensional barcode scanning items, the implicit information in interpretation of 2D barcode Two dimensional barcode reading software of the intelligent mobile phone has been very mature, this further promote the popularity of the QR codes in our country.
Automatic extraction of 1D barcodes from video scans for drone-assisted inventory management in warehousing applications

In the present time, there is little difficulty in recognising a barcode with a mobile phone camera or reading barcodes from most public barcode datasets when barcodes are usually intentionally focused on and occupy relatively large part of the whole image. Different from such situations, the difficulty in our situation arises mainly from multiple barcodes with unexpected direction existing in one frame and a much smaller portion of separate barcode regions. The fallout of this situation is that in the decoding phase, significant time has to be spent on searching recognisable barcodes in the whole image. Our proposed idea is to help find potential barcode regions for the decoding algorithm and thus save time by avoiding the processing of non-value-adding regions.
RFID network planning using a new hybrid ANNs-based approach

In the face of current technological advancements and modern production processes, ‘barcode’ technology has proven useless for identifying and tracking things, particularly in IoT applications (Elbasani et al., 2020; Figueiredo e Silva et al., 2018; J. Zhang & Tai, 2022). As a result, radio frequency identification (RFID) is being welcomed as a reliable and effective solution to many of the difficulties brought by recent technological developments, modern manufacturing, and service automation (Altaf et al., 2018; Xiao et al., 2021). The implementation of an RFID system requires four basic elements: readers, antennas, tags and middleware.
