CALLING ALL INVENTORS: Make a Quick Checkout Body Scanner Answered

Can someone PLEASE invent a body scanner (like a metal detector that you walk under/through) that is used in store checkouts to speed up the process and make waiting times less for lines??

I imagine it would work something life this: the tags on the items would have special chips in them (and/or metal pieces for quick detection of how many items you have), so that when you walk under the scanner with your shopping cart full, or stuff in your arms, it nearly instantly calculates how many items you have and at which prices. Then you can use your card or cash to pay for your purchase in that same machine (like an ATM).

Would be BRILLIANT! Thanks :)

Such scanners already exist, in principle - RFID technology.

What you need, though, is for RFID technology to come down even further in price, and for manufacturers to include RFID tags in the labelling of all their products. Once that happens, an RFID reader could check everything you carry (but you'd probably need the scanner to be in a queuing system, to prevent you getting charged for the things bought by the people on either side of you).

All what you said plus that ALL manufacturers would have to put those tags on their products. Took years to get them even to print an EAN barcode - and even there is the fall back solution of having the code in clear text printed.

And you will still have to put the stuff you buy on a belt. Or would you like to pay again for that box of peppermints in your pocket (that you paid for weeks ago of course - not one you just stole) every time you pass such a portal?

The contactless payment is solved too: NFC.

Hmm... wonder if there's a way of disabling a tag as it's read?

Some RFID tags can be re-written so, theoretically, you could 'erase' the info in the tag as it passes through the checkout and then you wouldn't get charged for your mints again.

BUT, you guessed it, it would be simple to bypass the shop's system by constructing a device that lay in the bottom of a thief's backpack that erased the tags as they were added - instant free stuff!

Barcodes are 'read-only', and optical, so have to be seen to be read.

FWPs, eh?

lol good points. The human race is definitely smart enough to figure this out and with fixing all the problems listed here (like price and re-paying, etc). There's some brilliant idea out there will work, I just know it. :)

this may sound stupid...but what about a take on sonar (like in subs) where it sends back pings to let the machine know there's different items all passing through? Maybe start with this type of theory but add to it that the machine can also read all the diff prices when pinging etc. Or like a giant barcode scanner that can somehow read all the diff tags at once? Idk just brainstorming theoretical ideas...

That's what RFID does - the scanner pings a signal, the chip pings it back.

Sonar wouldn't work (ever seen an ultrasound scan picture?).

lol sorry idk all that tech jargon....my bad. But I know what an RFID is...just not all how it works. Back to the drawing board

are there other options besides solely RFID chipping everything?
