In the past two decades or so, shopping has really evolved. Previously shoppers all over the world had to do a time-consuming process to check item prices. Manufacturers and resellers went through the same process. Adding prices or tags to each item requires a lot of time. Now, things have changed. Perhaps, a huge contrast to what most people experienced in the past decade.
Since the pricing process has changed, the way people shop and sell their products has also changed. Now, customers can leave the store in mere seconds after shopping and receive the bill from the store.
The reason behind this is the existence of barcodes. In the event that you were living under a rock in the past years, a barcode is a product lookup code that is made up of the lines and numbers that you see.
1. QR Codes: which allow mobile phone users to react spontaneously to printed material (posters, real estate signs, door signs, business cards, packaging, ads, coupons). Instantly connect the Real-World to the Internet!
2. UPC Barcodes: When you go to a grocery store or open your refrigerator, chances are you will see that almost every product has a printed UPC barcode. In fact, almost every product in the United States has its own UPC barcode, whatever type of product it may be.
So what are UPC barcodes and what are they for? Universal Product Codes, or simply known as a UPC, is a 12 digit long number that appears on the majority of all United States products. These barcodes were originally intended to help grocery and department stores speed up their checkout process.
Also, through these UPC barcodes, grocery stores and companies are able to efficiently keep track of their inventory. UPC barcodes were designed for mass circulation and tracking of products.
3. EAN: The International Article Number (EAN) (also known as European Article Number, which technically refers toEAN-13) is a 13-digit barcode symbology, which is a superset of the original 12-digit Universal Product Code(UPC) (also known as UPC-A), developed in 1970 by George J. Laurer.
