What happens at a store when items have the same barcode?
I understand that bar codes are “only” 10 or 13 digits, naturally limiting the available possibilities. But since there are sooooo many different products, how can a store, e.g. Walmart, differentiate if lets say a deck of cards and a pack of Aspirin have the same bar code? How does the cashier know what’s up, and how does the register react anyways?
Best answer:
A 10-digit number has 10,000,000,000 different possibilities. There aren’t that many products for sale. No two products will have the same UPC code.

How is it that no barcode is the same? What about online barcode generators?
Yes, there are actual barcode generators! Are these things safe to use and sell with to a place like Walmart, for example?
Best answer:
Actually there are dozens of different types of barcodes – at this website you can code your own.

Are the barcode label and the EAS soft tag one and the same thing?
The barcode label is the label that the scanner in a store reads to get the price, etc. The electronic article surveillance (EAS) tag is the tag that is deactivated upon purchase so that one can pass through the EAS detectors at the exit without tripping the alarm. This is how I read my sources anyway. But aren’t they one and the same thing?
Best answer:
No! the [EAS] is only there to stop shop lifters and is added by the store in many cases. The bar code or UPC is placed on the item by the manufacture and ID’s the maker and the price to be charged.

How do I scan my library card’s barcode to print it in the same proportion?
I want to do this because I don’t like carrying around my library card, it could get lost and etc.
I have a scanner by the way, but every time i scan it’s too large.
Best answer:
Your scanning at a higher dpi so the printer prints at that.Print and 100 %
Scan at the same DPI the your printer is set at.
Most likely 300 dpi. check your printer setting to find out. match the printer settings with your scanner settings.

Can I have two printers connected to my Mac at the same time, via USB?
I have an eMac (running MacOS 10.3.9) at home, as well as an inkjet printer/scanner/copier (aka all-in-one) and a laser printer. Would like to connect both to the eMac, via USB, using only one at a time. Is this feasible, or would I have to plug and unplug the cables?
Best answer:
If you had a network it would be possible.

Do re-issued passports carry the same info on the bar code as the previous ones?
My friend has an overstay file, but has not been banned to united states. Will his file show up on the border when they swipe his new passport and will he automatically be flagged for check? Thank you
Best answer:
Re-issued passports contain all the same information as the original passport – that information stays on your file (even if it’s no longer an active issue) your entire life. So, if he would still be getting flagged on his old passport, then he’ll still get flagged. It’s all in a database – the passport itself doesn’t matter. It’s tied to your passport number, and that doesn’t change.

If I printed out a barcode, would it scan in the same places a drivers license would scan?
Please no lectures on the consequences of fakes, I already know.
No lecturing.
This site says you can:

The barcode is pdf417. I originally thought the scanners they use at bars used magnetic reading, however, most barcodes on licenses use pdf417. Thing that confuses me is I see no readers where you slide a card and it reads pdf417.
Best answer:
Probably not. Most bar code systems are proprietary, and are not compatible with other systems, despite the fact they look the same.

how come barcode scanner can scan barcode upside down with same results..?
When you scan a barcode straight or upside down how come it still comes up with same results….
i thought scanning was identified by the space between stripes…..
Best answer:
It can tell by the thickness of the first and last strip which way to read from.
