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.

Printed barcodes have grown in demand as they play a key role in our daily lives to take control of any stocks in the markets and industries. Barcodes are read by a barcode scanner using the principle of light reflection from their black and white bands. There are three types of barcode scanners: Pen scanners: A photodiode measures the intensity of the light beam reflected on the barcode. It is manually scanned at a proper angle under a specific speed via humans.Charger coupled device (CCD) scanners: A photodiode measures the intensity of LED beam reflected on the barcode.Laser scanners: A photodiode measures the intensity of the laser beam reflected on the barcode. It is automatically scanned at a proper angle under a flexible speed via oscillating mirrors. The angle of view (θ) of the laser scanner (Fig. 6.5) is written as θ=2tan−1L2F where F is the focal length from the laser scanner (i.e., F = 50 mm), L is the scanning length of the barcode (i.e., L = 12 mm), and W is the scanning width of the barcode.

A barcode scanner is an optical device that reads the code by scanning a focused beam of light, generally a laser beam, across the barcode and detecting the variations in reflected light. The scanner converts these light variations into electrical variations, which are subsequently digitized and fed into the decoding unit, which is programmed to convert the relative widths of the digitized dark/light spacings into numbers and/or letters.
Clinical profile of the SEM Scanner — Modernizing pressure injury care pathways using Sub-Epidermal Moisture (SEM) scanning

SEM Scanner values are recorded as an integral component of patients’ records. They remain available in the medical records following the transfer of patients between care settings, between admission, daily during the episode of care, and at discharge. The SEM Scanner 200 contains an integrated circular coaxial sensor, and a single (action) button is used to turn the device on, reset it, and turn the device off (Figure 1(a)). The Provizio® SEM Scanner system (Figure 1(b)) is an enhancement of the SEM 200. It is available in three variants: (a) a separately supplied single-use, non-sterile, single-patient use sensor with manual entry of patient ID, (b) a single-patient use sensor with an integrated barcode scanner for patient ID, and (c) a fixed-head sensor with an integrated barcode scanner designed for research purposes.
Where to locate medical supplies in nursing units: An exploratory study

For Hospitals A and C, the main replenishment system is par level. Rounds of the nursing units to be replenished are conducted according to a predetermined schedule. During the rounds, a storekeeper takes inventory of medical supplies on the nursing unit. The quantities counted are entered electronically using a barcode scanner. The information is then downloaded to the information system in the central storeroom, which compares the quantities counted with established quotas and generates a picking list or a purchase requisition in the case of non-stock items. The picked or ordered supplies are then delivered to the nursing units and put away by a storekeeper. In both hospitals, approximately 15% of all replenishment transactions are not managed by logistics staff.
A model-based framework for increasing the interdisciplinary design of mechatronic production systems

After the system has been modelled in a first step (during the development phase), a change situation is simulated. Therefore, the barcode-scanner in the handling station (Figure 13) shall be exchanged by a RFID-reader. Such changes occur often during the usage phase of production systems, e.g. because new technologies are available (RFID instead of barcode) or new functionalities shall be integrated (RFID-tags allow to store much more specific product information in comparison to a barcode).
