Role of Barcode in OpenCart Point of Sale

Updated 20 October 2022

Using the Opencart Point of Sale System a merchant can create orders for the products purchased by the customer from the physical store.

The Opencart Point Of Sale System facilitates hassle-free transactions and the customer can place orders either from the physical store as well as from the online store.

What is a Point of Sale System?

Let us take any grocery store’s example, for instance, Walmart.  A customer visits a Walmart store, purchases products and proceeds to a billing counter.


The cashier scans the barcodes of the products, and the details of the products instantly display on a POS machine. The merchant then tabulates the bill and provides the same to the customer.

The POS (point of sale) has eased things for a merchant in a way that it has reduced the labour of jotting down each product along with its price on a register and tabulating it.

This can be a tedious task as noting down details of each product for a long list of products is nearly a waste of time and until then the customer’s queue may increase and some customers may leave due to waiting in the queue.Barcode in Opencart Point of Sale-4

What are the Barcodes?

While buying any product we must have encountered parallel lines separated by spaces, printed on the product.

These are machine-readable codes that the sales agent scans to retrieve the details of the product.

A barcode consists of five parts- a quiet zone, a start character, data characters, a stop character and another quiet zone.

  • The quiet zones- They ensure that any data which does not relate to the barcode is being picked or scanned.
  • Start/Stop Character- Indicates the start and end of the data. They are different for different Barcodes.
  • Data Characters- The bars of the barcode which represent the data. A check character follows the data character which is a numeric value for the calculated error.

Importance of the Barcodes

Using barcodes the user can easily track the product inventory and get information about the products. The labour of entering the data manually minimize and it saves a lot of time.

  1. It eliminates the risk of error that is caused while entering the data manually. The data scanning through barcodes is comparably fast and takes less time.
  2. A merchant can easily handle and scan the barcodes for products using a barcode scanner, which increases the efficiency of the merchant.
  3. The barcodes help track the inventory of the products precisely. The location of the product can be tracked easily, no extra time is wasted in searching for it manually.
  4. Barcodes are easily created and the cost of creating them is also less. They are easily customizable.
  5. When the agent scans the barcode, the product data is directly fed into the computer. Therefore the data is available instantaneously unlike in manual data entry where you have to scan the whole register to find the details. 
  6. The details of the product are accurate and reliable. The sales agent may fill in erroneous data while entering the details of the products.
