Uses of Digital Devices 2
Retail Uses
Electronic Point of Sale (EPOS)
An EPOS is a computerised checkout till. It uses digital devices to record sales and take payments for them.
For example, barcode readers are used to add new products to a sale and optical mark readers are used to input lottery tickets.
Magnetic ink character readers verify cheques and chip-and-pin devices process card payments.
We can even make contactless payments using our mobile devices with Near-Field Communication (NFC).
This has made the sales process more efficient, increasing speeds & reducing errors.
We now even have self-service EPOS systems, so you don’t need a sales assistant at every till.
Stock management
Database management systems that run on servers will connect to the EPOS systems.
When a product is sold, this information is sent to the server, & the database will be updated with the new reduced stock level.
Our stock management server can also be connected via the Internet to the servers at our warehouses.
This allows the system to order new stock automatically so that the new stock will arrive before the old stock runs out.
So much of the process of monitoring stock & making orders can be automated that we can save money with fewer admin staff.
This also helps to reduce human error in recording stock levels & ensures that you both don’t run out or order too much stock.
Retail websites
Most shops have e-commerce websites, which they use to sell and advertise their products over the internet.
To run an online website, all a business needs is a web server to host the site and a PC to develop and maintain it, such as updating prices and adding or removing items.
This is very cheap to do when compared to setting up a brick-and-mortar store.
An additional benefit to the business includes being able to sell their products to a worldwide audience rather than just to people who live in the surrounding area.
They can also make sales 24 hours a day 7 days a week.
Manufacturing Uses
Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM)
One significant way digital devices are used in manufacturing is through CAD and CAM systems.
CAD software allows designers to create detailed digital models of products before they are physically made. These models are more accurate and easier to modify than traditional drawings.
CAM systems take these digital designs and use them to control machinery on the factory floor.
For example, a CAM system might control a CNC (Computer Numerical Control) machine to cut metal parts with precision. This ensures the manufacturing process is consistent and efficient, reducing waste and costs.
3D Printing in Manufacturing
3D printing is a revolutionary way digital devices are used in manufacturing. Using a digital model created with CAD software, a 3D printer builds a physical object layer by layer.
This technology is used to create prototypes quickly and cost-effectively. For example, car manufacturers can produce prototype parts to test designs before moving to mass production.
It also enables manufacturers to produce custom or complex parts that would be difficult or expensive to make with traditional methods.
3D printing reduces waste, as it only uses the material necessary to build the object. It also allows for rapid adjustments to designs, improving the efficiency of the manufacturing process.
Quality Control and Monitoring
Digital devices are essential for quality control in manufacturing.
Sensors and cameras connected to computers can inspect products on the production line. These systems can detect defects that might not be visible to the human eye.
For example, a camera system might check the dimensions of a part to make sure it matches the specifications. If the part doesn’t meet the standard, the system can alert a worker or automatically remove the faulty item from the line.
Digital devices can also monitor machinery to ensure it is working correctly. This is known as predictive maintenance.
Sensors can detect when a machine might be about to fail, allowing repairs to be made before a breakdown occurs. This reduces downtime and keeps the factory running smoothly.
Healthcare Uses
Digital Imaging and Scanning
Digital devices are essential for modern medical imaging.
Equipment such as X-ray machines, MRI scanners, and ultrasound devices produce detailed images of the inside of a patient’s body.
These digital images help doctors diagnose conditions more accurately. For example, an MRI scanner can detect brain tumors or spinal injuries that would be difficult to diagnose through physical examination alone.
Digital imaging also allows images to be shared easily with specialists in other locations, enabling faster and more collaborative diagnoses.
Electronic Health Records (EHRs)
Hospitals and clinics use digital devices to maintain Electronic Health Records.
These records contain all of a patient’s medical history, including test results, prescriptions, and treatment plans.
EHRs make it easier for healthcare providers to access a patient’s information quickly and securely.
This improves the efficiency of care, reduces errors, and ensures that doctors have the information they need to make informed decisions.
Patients can also access their own records online, which helps them stay informed about their health.

Creative Task Uses
3D graphics
The video game and film industry makes heavy use of personal computers for the creation of 3D graphics.
In the film industry, ‘CG effects’ have heavily replaced older-fashioned physical effects.
In almost every movie released nowadays, you see 3D models produced using digital devices.
This is because it is often quicker and more flexible, as changes can be easily made to a 3D model.
Similarly, most high-end video games use 3D graphics for the game characters and environments.
This has added a new level of realism to video games, and we’re even using Virtual Reality headsets to experience the graphics in 3 dimensions.
Photo & video editing
One of the biggest benefits of taking photos and videos using digital cameras is that we can load them onto a PC for editing.
Professional photographers now heavily use both digital cameras and personal computers for this purpose.
This might be fixing the lighting of a picture of a house that an estate agent is selling or removing certain objects from the image.
It could also be removing blemishes, such as spots or red-eye, from a photo of a person.
In addition, the movie industry relies on digital cameras and PCs for filming and editing, enhancing efficiency and flexibility.
Video editing software allows for quick edits, simpler corrections, and easy duplication for backup.
Graphic design
Personal computers with graphics editing and desktop publishing software are used to create logos, leaflets, brochures, magazines, books, and comics.
Once, graphic designers mainly worked by hand, including manually typesetting books by positioning individual characters on a printing press.
However, we now use desktop publishing software to design layouts and typesetting for books & magazines.
This is much more efficient than manually typesetting a book, which would involve the painstaking positioning of the individual characters.
We can also quickly send the data to printers, such as by email, to produce the final book, magazine, etc.
Automation & Robotics Uses
Industrial robots
Industrial robots are used in factories to perform repetitive and complex tasks.
These robots are controlled by digital devices and can work more quickly and accurately than human workers.
For example, robots in car factories assemble parts, weld components, and paint vehicles.
They can work continuously without breaks, which increases productivity.
Robots can also handle hazardous tasks, reducing the risk of injury to human workers.

Autonomous vehicles, such as self-driving cars, use digital devices to navigate roads and avoid obstacles.
These vehicles rely on sensors, cameras, and AI to make real-time decisions.
For example, delivery robots and drones are becoming more common in industries like retail and logistics.
They can deliver goods without human intervention, reducing delivery times and costs.
