Can a barcode scanner cause spots if aimed at my forehead ? Watch

    I bought a small mini barcode scanner (symbol cs1505 scanner) and I was curious to see how bright it was ( turned out to be very very bright )and shone it in my eyes a few times and the laser kept bouncing up and hitting my forehead. The next day I noticed small spots on the middle of my forehead, not bad spots but still not very nice.

    Just wondering, could the laser radiation from the barcode scanner have caused the spots on my forehead ?

    It is a class 2 scanner


    Thanks

    Nah it couldn't, you aren't meant to look directly at barcodes though so be careful there. Barcode scanners work by shining a light on a barcodes and then bits of light are reflected back by the white bits in between the bars and data is gotten from that. There's no radiation or anything really, it's just a red light

    Light is radiation. But beyond that you are correct.

    How do people remove the barcodes in a store to stop the shop alarms from tripping out ?

    The scanners dont detect barcodes, they detect sensors.

    I'm not sure, I was really just saying what I know from my IT a level. Though I do work in a supermarket and the items with just barcodes don't trip out the alarms if they aren't scanned, it's more a stock thing, the alarms only go off if they have security tags like the big grey things they take off bottles of spirits or off of clothes at the till. I may be wrong but this is just from my experience, hope it helps!

    Would swiping a magnet above a barcode stop the barcode from tripping the store alarm gates ?

    Contrary to most people beliefs barcodes don’t trip the alarms, it’s the tags which do. So if the item isn’t tagged, it won’t sound the alarm. But the supermarkets probably don’t want you to know that

    They don’t. Only tagged items do, I’ve worked in retail before. I know Waitrose tag products that Tesco wouldn’t because they have these flat green stickers with small metal pieces inside, only Waitrose use them though. Otherwise anything with a grey tag triggers the alarm, NOT barcodes.

    Lmao no they don't. A barcode is just something printed on the product/package. There is nothing there to trigger an alarm. It's ink.

    How do you magnetise some ink on a bit of card?

    I think what you mean is that the scanners can detect the sensor underneath a barcode.
