Write data on any surface ?

    write data on any surface ???

    hi
    i was in a meeting where a man presented
    a system ( called Promotron ) for write data "on any surface"
    in an "invisible" , "in-adulterable", "impossible to copy" way
    and then read it.........
    he never showed, by the way, HOW HE WRITES THE DATA
    and he said that the way of writing is a secret

    is it possible ???

    his intention is to replace clasics
    magnetic stripe cards
    by any object ( plastic card, cardboard, etc )
    using this system

    he said that this is a revolutionary technology......
    but i don't rely much in him
    i have looked for some system already invented,
    and i found "LSA - laser surface autenthication"
    by russell cowburn
    LSA method simply don't write , just unique surface properties
    i think the system that i seen
    is a like of copy of LSA

    what do you think
    can anybody guide me to "the truth" ?

    Could you offer more info? I can find no substantive reference on a Google search.

    As soon as he says any surface, ask him to do it on the surface of water.

    And, if the data is 'invisible', how does he read it?

    Personnally, if anyone told me that story I'd tell them to put up or shut up. I don't care about your 'top secret' writing mechanism unless I know it works (working model or theory acceptable)

    How much does he want you to invest to "perfect" it?

    Scram, it's a scam!!

    its just 1 0 of course u can write data to any surface.. as for water, how about some form of ionised ink

    Like Kleinjahr says: run, don't walk, to the nearest exit and never look back. The only way that you can achieve the effect that he's claiming is to permanently alter some physical characteristic of the surface in question, such as with laser etching or impregnation with another substance. The possibility of doing that is entirely dependent upon the surface in question, and would certainly require something more elaborate than he's making out. There's no chance that the same technique would work on stainless steel, balsa wood, and glass (as 'for instances').

    edit: Just saw your post, Anttech. Water is a dynamic substance. You'd have to keep it frozen in order to maintain a surface composed of the same molecules in the same places. There's nothing to write on.

    Not if u ionise it and keep it in a charged field, water also has surface tension, I am sure u could engineer that also

    Anyway the person u mention in the OP is talking pure tosh :-) And it certainly isnt a Revolutionary technology..

    If it were true it would be revolutionary.

    I agree not to invest in this (not without a much better demo).

    As far as what it might be:

    A hand-held device that prints and reads text using ink that shows up under UV light would fit this bill. Of ocurse, it's not going to replace any existing technology. I can think of a bunch of other techniques if given enough time.

    I thought of the UV pen thing too, Dave, but it won't fly. As an ex-screen printer, I can tell you for sure that there's no formulation of ink that will work on all types of surface, and all of them eventually wear off.

    Well that sure doesn't fit his description of "any surface" to say the least :P

    1] I am willing to grant some sales-hype here. I interpret "any surface" as "a range of select surfaces".
    2] There was no claim that it would not wear off.

    Right, Dave. I took 'un-adulterable' to mean 'endelible', but it's not the same thing.
