# How to use a Barcode scanner for Products

Clinicea supports the use of a barcode scanner in multiple ways. Let us look at how to use it for inventory.

 

Example: You have an in-house pharmacy and would like to use the barcode scanner while dispensing.

 

PRE-REQUISITES: THESE STEPS NEED TO BE DONE ONLY ONCE:
1. Go to **Inventory**– open up any inventory, Example: Aspirin.

2. **Inventory Details** | SKU (Stock Keeping Unit)- enter the machine-readable code you want to add to the Inventory Example: ASP101. You will see that a bar-code is generated automatically, Save.

 

**Note**:

1. The auto-generated bar-code must be the same code used for the inventory item.

2. No two SKUs’ can be the same for two different inventories.
