Using Bar Codes
From FloristWiki
You can scan products in the Order Entry and Point of Sale with a bar code scanner. To scan a bar code, your cursor must be in the Product Code field. When you scan the bar code, FTD Mercury checks to see if there is a product in the database that is associated with that bar code. If the system finds a match, the Product Code, Qty, and Description fields fill in automatically. If the bar code has a default price associated with it, the Amount field also fills in. If there is no default price specified, you have to enter the price manually.
If you scan a bar code that is not in the system, a window pops up asking if you want to create a new product with the scanned bar code. Click Yes to enter the bar code into the system, or click No to enter a different product code.
You may also perform product searches by typing in the full bar code for a product.
