Food barcode scanner
When you scan the barcode label on the product, it sends a signal to the database. If a database in your phone is too small, you need to connect to an online database. The barcode scanner keeps track of all items and can also provide other information such as storing data and deleting data.
Library barcode scanner
Barcode scanners are pretty common in our daily life, so have you ever thought about how the library system uses them? The ISBN barcode is printed on the back cover of books, and when you borrow a book from the library, the librarian will scan it to record your checkout transaction. This may look like magic to you, but actually it is a barcode tracking system that’s composed of a barcode reader and a database.
When you borrow or return a book at the library, the librarian will first use a handheld scanner to read and decode the ISBN barcode on its back cover. The scanned information will then be sent to database through wired or wireless connection for data processing. You may also witness this process by watching an animation at some libraries: what looks like red laser beams coming out of your books turns out to be code scanning!
After scanning your book, database management software will locate matching records in its own database and update relevant information based on that. For example, if you are borrowing this book for the first time, it would be marked as “Checked Out”; otherwise it would remain “In Stock”. Then you can sign up for an account with your name and address in case there are any overdue charges later on.
Cash register with barcode scanner
- Barcode scanners are small devices that can be used to read and output printed barcodes. They’re often used for inventory control in retail settings, but can also be useful for other purposes, such as verifying the authenticity of a product or computing moving averages on stock-market data. If you own a barcode scanner, it’s worth knowing how to use it.
- The cash register is an electronic device that can be programmed to take payment from customers and return change directly into their pockets. When this part of the business doesn’t need to be automated, consider investing in a barcode scanner instead; they’re more versatile, cheaper (a typical cash register costs around $50), and easier to maintain than a cash register with no barcode reader feature.
- Programming requires the user to input specific information about products or notes about its sales transactions using a computer before it can transmit the information for processing by the retailer’s accounting system. It may sound complicated at first, but even if you have absolutely no experience with computers or programming languages like HTML and CSS, there are some simple ways for beginners to learn how these things work—for example, online courses available online through sites like Udemy or Codeacademy.
Barcode scanner is applied in many aspects of our life.
Nowadays, more and more places are using the barcode scanner, but there is some place where do not use it, such as a supermarket. With the development of society and technology, we can use barcode scanners in many aspects of our lives.
First, we are familiar with barcodes on foods in supermarkets. For example, when we buy something to eat in the supermarket or restaurant, waiters will scan the food’s barcode by hand-held scanner before they sell it to us.
Second, almost every bookstore has a library card that is able to scan books’ barcodes which you borrow from the library. It is convenient for librarians to manage books by scanning their barcodes because this method saves time and ensures accuracy.
Thirdly, cash registers with built-in scanners have become increasingly common as a way of reducing time spent at checkout stands and increasing customer satisfaction through faster service.
