In this blog I will be focusing on EPOS: Electronic Point of Sale which is, in my opinion, one of the handiest information systems which has been in IS or many of years. It is accessible in every shop which is a huge help to everyone involved. First and foremost, The checkouts would be piled with people without EPOS as it is such a convenient way for products to go through. The system scans the product and the information from that barcode would be sent to a head office system to search for the relevant information (EAN number). This allows for all products scanned through in a shop to be match instantly to this EAN number and the relevant information comes up on the screen. This is particularly handy due to the fact that shop assistants don’t have t manually enter the data or even worse, remember every price of every product.
Their basic functions include scanning bar codes or radio frequency ID (RFID) tags to identify products, scanning credit cards, and cash handling. Epos do not just handle transactions but also help management in decision making by connecting to an information system that allows for information on sales instantly. This also helps in logistics and stock control. In supermarkets and shops they have various ways of recording stock and checking stock levels and also ordering and delivery purposes which is conveniently done by using Shelf Edge Computers. They may seem like minor things but in fact every shop would be lost without it.
Without Epos, doing a simple shop wouldn’t be so simple anymore and we could end up spending hours in a shop instead of only a few minutes.
