A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes.
A bar code scanner reads bar codes.
Bar codes contain data, typically numeric or alphanumeric data. While bar codes may all look the same to people, the data and even the "symbologies" are different. A bar code symbology is sort of like the language of the bar code, and there are many types: UPC, EAN, Code 39 (also called 3 of 9) and many others.

Is a bar code scanner also called a handheld scanner?
There are handheld bar code scanners, so a handheld bar code scanner is a bar code scanner, but a bar code scanner is not necessarily a handheld scanner. There are bar code scanners in store checkout stands that are fixed, and there may or may not be an associated handheld scanner there for the clerk to use to scan, say, a large bag of dog food that the customer doesn't want to hoist up onto the counter.

That other information could include what the item is, its price, brand, size/weight, and many other particulars. The scanner is able to identify the item, and once the bar code has been used for that, the computer server does the rest.
