Discussion Overview

The discussion revolves around a system called Promotron, which claims to write data on any surface in an invisible, in-adulterable, and impossible-to-copy manner. Participants explore the feasibility of such a technology, its potential to replace traditional magnetic stripe cards, and the lack of transparency regarding the writing mechanism. The conversation includes comparisons to existing technologies like laser surface authentication.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the feasibility of writing data on "any surface," questioning the validity of the claims made about the Promotron system.
  • Concerns are raised regarding the lack of a demonstrated working model or theory to support the claims, with some suggesting that the technology may be a scam.
  • One participant proposes that writing data on surfaces could theoretically be achieved through methods like ionized ink, but acknowledges the limitations of such approaches.
  • Another participant argues that achieving the claimed effects would require permanently altering the physical characteristics of surfaces, which would vary significantly between materials.
  • There is a discussion about the challenges of using water as a surface for data writing, with differing opinions on whether it could be manipulated to serve this purpose.
  • Some participants suggest that the term "any surface" may be an exaggeration, interpreting it as applicable to a limited range of surfaces instead.
  • Participants speculate on alternative methods, such as using UV light, but express doubts about the practicality and durability of such solutions across different surfaces.

Areas of Agreement / Disagreement

Participants generally express skepticism and disagreement regarding the claims made about the Promotron system. There is no consensus on the feasibility of the technology, with multiple competing views and uncertainties remaining in the discussion.

Contextual Notes

Participants highlight limitations regarding the claims of the Promotron system, including the dependence on surface characteristics and the potential for wear over time. The discussion reflects a variety of assumptions about the nature of data writing and the materials involved.

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" ?
 
Computer science news on Phys.org
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 isn't 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.
