Paying cash means you cannot be tracked? - think again!

[Greebe]

No you've not been nice lately, you've only been temporarily humbled.

Have a bad day at work Jason?

If you only knew the slightest about what I am refering to (like antenna needs to be 25cm² to work) you're sadly mistaken. Did I say it was rfid? Nope, but go ahead and jump off the deep end, it's what you're best at.

[Gurm]

Ok lemme recap:

Us: That won't work, the antenna has to be much bigger.

Greebe: You have no idea what you're talking about.

Gurm: Yes we do, hush.

Greebe: No. The antenna has to be bigger. You're a moron.

Who sounds stupid?

Oh yes, that's right - you!

Now be quiet. You can no longer call in favors and have my posts erased, or had you forgotten?

No 5cmx5cm=25²cm... ie what tjalfe said...

Stop thinking antenna's and think frequency. Higher the freq. shorter wavelength ie antenna is needed... jump into the microwave range and it's all the same.

What an additude... tsk tsk

Dredging up the past are we... Boy do you have it bad... and incorrect. I don't pull favors, only what is agreed with is delt in an appropriate manner or don't YOU know the difference? (more baseless flames... how sad)

Most of your comments are rather amusing

Perhaps you should work on your delivery, you come off sounding like you're saying "You're all wrong, I know the truth but I'M NOT GOING TO TELL YOU, HAHAHAHA!"

All in how it's interperated Jon.

I've had several members (friends) jump my case privately over how I've stated things before... then they come to find out why I do and understand.

Sometimes not, but mostly they do.

Just because I don't spell it all out in the simplist form doesn't mean I'm only trying to come off as a smart arse 24/7 (unlike some people).

Sometimes I do only to provoke others to ask additional Q's and to think about what they're saying.

If Jason wanted advise I'd give to the best of my abilities... he seems to think I hate him, I don't. After having a run in with Buddman (and the subsequent barrage of spam emails he signed me up for) He asked some Q's of all and I answered them for him without ill repute. He even thanked me and that wasn't neccessary (but nice

There are certain people do recieve my special treatment... and there is always good reason behind it.

Sooooooooooo...

If ya have a Q just ask.. I can be reached many different ways. (PMing, email, etc. etc.

[Tjalfe]

then I ask, what is the read range of a tag small enough to be in a $20 bill?...
I only ever worked with 125KHz and 13.56MHz systems( and that was 2 years aog), and the read range was miniscule. I have seen some companies advertize huge range on a passive tag, but I do believe it is a highly directional antenna and much higher wattage that is allowed here in North america

So what are your experience with RFID?

[Greebe]

My experience... just about everything that has electrons running through it. Both on the commercial/industrial and the military/goverment side of things.

I did not question your overall experience, which I can tell is way beyond mine, but what info do you have about RFID?..
My experience is based on working with it 2 years ago, so I figure you may have something new to add to it since.
Is there a wonder tag out there which somehow can be read at a decent range and be small enough to be in a $20 bill? .. I have not yet run into such a beast, but it would have to be in the 2.45GHz or 5.8GHz range to have an antenna small enough. ( these standards were not around when I was working with them)

[Greebe]

opened a can of worms here... how should I say... uhmmm...can't. Lets just say @~15gHz interesting things are possible

[az]

I seem to recall (though I of course have no real knowledge) reading that there are passive RFID tags with half a meter read range that can be hidden in clothes labels.

AZ

[Tjalfe]

@ 15GHz you are working with black magic

[Greebe]

lol

yup, iirc benetton started using them. the EZB might have plans to include RFIDs into €-notes, these consideration were confirmed by a spokesperson at some point last year. I only found a reference to an EE times article, which seems to be gone.

How come nobody paid attention to the followup.. they are NOT putting RFID tags in their clothing.
Also if they ever are put into clothing, what is keeping people from cutting it off if they are so concerned about privacy

"The Italian company Benetton said in a release that it "is currently analyzing RFID (Radio Frequency Identification) technology to evaluate its technical characteristics and ... no feasibility studies have yet been undertaken with a view to the possible industrial introduction of this technology."
