RFID jammer

Hello everyone.

In short: RFID is a technology that transfers information from chip to RFID receiver placed at cash desks etc and could be anywhere.

Does anybody have schematics or instructions how to build an RFID jammer?
Or do you know a device which jams RFID signal and I can unflashily attach to my belt or put it in my pocket? I ticked disable digital crap on my ID card, but I don't rely on that.

A hentai forum isn't exactly the best place to be asking about this sort of stuff. Also there's legal implications using radio frequency jammers.

The easiest way to stop a reader picking up your ID cards is simply to use a Faraday cage otherwise known as aluminium foil.

I'm sorry, but isn't this the special interes >Computers and Technology section?
But thanks for the aluminum foil tip. But what if the police demands my ID card?
Wrapping it in Aluminum foil to prevent RFID capture isn't necesary illegal,
but it might be noted.

Here's why it's not the appropriate place to discuss the making or purchase of one of these devices - It is *illegal* to have anything that jams radio frequencies.

As far as cops seeing aluminium foil around your ID they'll just pass it off as you being a bit paranoid. But if they notice their radios cut out they'll get much more suspicious.

what do you want to do with it if you have one?

Nothing. I feel a sensation of being watched by the police for quite a time. I came across 3 or 4 police cars in a time span of 15 to 20 minutes in Town a few weeks ago for example. That's unusual in my town to see so many police cars. That intimidates me. I haven't done anything wrong. Either it's my interrest of firearm sports (family custom), possess something questionable or I'm a suspect of destroying waspnests or a pyromaniac or whatever the German government has a problem with. I don't know. They have so tough laws.

NSA and CIA are not my concern. They've been spying on people for decades.
They get any information about me anytime and anywhere anyway. However, I'm not the guy who complains about it. I learned to deal with it many years ago. But I don't grand the German government any opportunity to track me. They are just too unimportant to get informations about me.

In short: If I had one, I want to limit the potenial of the Government of my Juristinction and corporations to obtain any information about me.

Mate if I was a cop I'd be asking questions right now. Considering the issues the EU has right now it's probably not wise to use an *illegal* method to 'hide' from the authorities you're basically asking to be questioned and arrested by the cops for possessing such a device.
