what makes a scanner in a grocery store work?
340206
The scanner sends out a laser beam that reflects against the barcode on the object. The scanner is programmed to recognize the reflections of barcodes and use those to identify the product.

Make sure you know what you want to listen to and what frequencies they use.\n\nEven if you buy a cheap one, you might be wasting your money if everything around you is on a digital 800 mhz trunked system (like my county) that requires a $500 scanner. \n\nAnyway best deals are garage sales, close-outs (Radio Shack, wal-mart),  and as mentioned, eBay.

Excerpts from http://securitytags.biz/\n\nSecurity Tags refer to the sensor tags, hard tags, paper tags, security labels, AM tags, RF tags and other EAS tags detected at the front door of a retail location by a security detection system. These security tags serve the function of alerting a retailer that security tags or sensor tags along with the clothing they are protecting are leaving the store.\n\nSecurity tag detachers refer to the security tag removers, magnets or locking mechanism openers located at the check out area of a retail location. These Tag Detachers serve the function of opening up the security tag and allowing the security tag or sensor tags removal from a garment. Every security hard tag system needs a detcher.

Automated Teller Machine\n\nTeller as in bank teller.  Basically it's like a doing a bank transaction w/o a real person, so it's an "Automated Teller".

The first place to look is at the website of the scanner's manufacturer. If you can't find the site, check the documents that came with your scanner for a tech help hotline. If those options fail, for whatever reason, you may wish to check the extensive library of software drivers that are available at www.software.drivers.com - click the link below, and you'll be taken directly there.\n\nGood luck!

Radio Frequency Identification.  This is where passive electronic tags are put into goods (e.g. think like the security strips at the store, but smarter in that they contain way more information or perhaps a non-powered version of the electronic toll pass in your car). The goods are passed through an electronic gantry that scans the codes and passes along the information.  That way you know everything that is in a pallet, container or box - how many, what color, what size, where they are from, where they are going.  All that time spent counting and categorizing by person is now done via technology. \n\n\nPros:\n1. Faster inventory velocity through the supply chain\n2. Lower costs of logistics\n3. Higher visibility of goods when in transit\n4. Lower shrinkage due to less container packing/unpacking/inspection\n5. Lower inventory levels needed as inventory can get more efficient. \n6. Lower total cost to consumer\n\nCons:\n1. Higher initial costs to logistics suppliers (who have to buy RFID systems)\n2. Fewer safeguards.  RFID tagged containers are sealed, which means less eyes on the container from origin to destination.  US Port Security acts means they may be inspected once they reach the US port, but it is only on a sample basis.\n3. Higher barrier to entry against competition as Walmart builds its cost advantage against competitors (i.e. you start to worry about anti-trust issues). \n4. Concerns that success at commercial level would spill over to personnel level, which would infringe upon personal privacy issues. However, electronic building passes already use this technology.

here goes...i will only give you a couple since i am trying to get a patent on some ideas of my own...\nthe grocery finder! its an electric device that is on grocery carts to help people find exactly where an item is.\nyou type in the name ,like cherrios,then it tells you what isle it is and tells you how much it is,and what size boxes they come in.(you dont even have to type in the word correctly,it will bring up any words that look the same)\nit helps keep the employees from having to walk each customer down an isle,and helps the customer from being frustrated from having to find an employee to help them find their product. (it could work anywhere...not just grocery stores)\na car cover that prevents hail dammage!   (that might already be out but i did think of it first along time ago)\na sweat suit that makes you cool and warm...battery powered\ni have more but i cant give them away

Let's see:  Computers controll the traffic-light system on your way to work.  They controll and monitor satellites, which in turn have lead to the highest crop yields in history, making the abundant options to the question "Why should I have for breakfast?" possible.  Computers track the movement of shipping trucks and other inventory, making it possible to efficiently track and count every item in our stores, which makes supermarkets filled with a large assortment of food of uniform quality possible.  The phone switching network is completely automated in modern countries, so you can't make or recieve a call without a computer helping out.  Computers do lots of things.

Buying a all-in-1 machine is the best route.  You'll have warranty protection, updated features and drivers, and save some desktop space.\n\nFurthermore, the older scanners will no longer have drivers for Win XP and beyond, and no technical support whatsoever.

For some reason it scans everyday. That scanning is most likely making your computer slow. Unfortunately, in the free version you can't set up a scanning schedule. So either have it scan everyday or turn it off and make sure to manually start a scan every now and then.

Convenience and time savings.\n\nIf I can store my grocery list on the company website, and just check the items I need and have them delivered...great!\n\nIf I can put in a standing order, and have items shipped with some frequency, so I don't run out...better!\n\nIf the company automatically offered the best prices and gave me a discount as sales were run, I would be a customer for life!

Place on scanner, ask for OCR (Optical Character Recognition), scan, and proof-read

You can buy a simple Radio Shack police/fire scanner. Essentially the same thing, but a much lower price.

As mentioned above, a scanner can be used for putting a picture or text onto your computer. If you haven't seen one, they mostly look like very small copy machines(with the glass window where the object is placed). I doubt you are referring to the radio scanner, but they are devices that scan through a set of frequencies you enter, so that you can hear the police ar other emergency workers talking over their radios.

I would look into the system used by EZpass on highways and certain medications.RFID tags. They are usually from two to four square inches in size, and contain a silicon chip that holds a unique string of numbers identifying the item to which it is attached. A separate RFID "reader" receives the information contained in the tag through the tag's antenna. Unlike a bar code, the signal does not have to be read directly by a scanner; RFID signals need only to be in the vicinity of an RFID reader.

no it's doesn't work it only send your some stupid coupons and when those stores are having a big sales.\n\nit's a waste of time
