Help with barc-ode info, how does it work?

When you have an item like a pair of pants for example does the bar-code on the label actually contain any information about the product like size, color etc. or does it only relate to a record you already have in a database.

In other words if you have 100 items of different types would a bar-code scanner help put that info in a data base or does it only help if you create a record first and associate it with the code number and then scan many of the same items?

Would something like MS Access be able to be used with a bar-code scanner?

Thanks for any help.

Normally is a number that identify the product in the database. So you have to enter that information in the database.

Now there are industry standards such us the Universal Product Code, you might want to check this site:

Yes, it can be any database. The bar-code scanner is just another input method, think of it as a keyboard, but you don't have to enter the code manually.

Is it possible to get a database from manufacturers of all their codes that lists details for the item?

There is an i-phone app that reads a bar code from almost anything and takes you to product information and usually a place where you can buy the item. I have seen it get a notebook confused with a tin of peaches, but it did correctly identify most of the items we showed it.

You should ask the manufacturers to provided you with their upc database.

There are also some databases you can get from the internet. You can get them from Gregg London (but they are not free)

Also there are some on-line upc databases, such us:

If I buy a t-shirt in a grocery store or buy a package of food, the same scanner is used.
Both items have bar codes.
I can tell you how the bar codes on food items work, since it is the same scanner that would scan a t-shirt or other non food item. Grocers carry tools, etc. not just food.

Some codes allow you to buy a different variety of food item, other than the specific one shown on the front of the coupon, as long as it is the same brand. Others do not allow you to do this.

So, yes the code can have identifying numbers, etc.

Some food coupons, that begin with a 9 on the UPC code can not be doubled.
This would not apply on a clothing item, but I am just giving you an example of how the UPC codes can affect-influence the pruchase. And the codes are put there by the manufacturers.

In the food coupon world there is a new movement to change the codes so that they do not have any numbers at all. This may apply to all items regardless of food or not.

The new codes are forcing the stores to upgrade their scanners.
An example of this is a store in the USA, called Target. The new codes, when the item is purchased, the cashier has to cover up part of the UPC code, so the scanner only picks up the part that will scan properly.
