Having barcode system in your store makes things so much better. This is especially true for those in the grocery or supermarket business where you need to punch in many things for a single customer.
Instead of using the calculator with printer, having the barcodes on your products and the barcode scanner in place will just expedite the process at the counter. And it will be less effort for the cashier as he or she works faster.
The new barcode system will even make things easier to check, balance, and inventory your stuff.
In our store, we do not really need it because the traffic of people is not that fast because the things that we sell are not commodities. So we need not invest in this system.
