or better yet, chip his most powerful focus, you watch him get rid of that. As a GM I use tags for everything, sometimes Johnsons will give runners tags to monitor progress, other times they placed in food, fed to the runners, which provides about a day and a half of tracking, which is good for short runs (you just have to be careful in that reguard that they don't scan everything they eat, and make sure the food is cooked very well). When I play, I wipe all the chips in my gear, and put fresh security tags and hidden tags, into each piece of gear (as far down, depending on the GM, as each bullet), just in case it gets stolen or I don't quite kill the drek that keyed my bike. RFID tags IRL, are not as safe as you'd thing, concerning range. A passive tag, which is what I assume your having implanted (else you'd have to have surgery every month to change the batteries, lol), has been proven to respond wih little signal distortion, up to a distance of 67 feet (which is the current world record, set at Defcon 13, intheshadows.tv, box 6). Also it is very possible to jam an RFID tag, with a relatively simple electronic device, I found the schematics online (also covered by intheshadows.tv box 6), and have every intention of building one, and testing it the next time I'm at Walmart. Theoretically you could severly hamper the progress of a distrobution center that has switched to RFID enabled barcodes by simply turning a device such as that on, and leaving it near the facility. |

Of course, it wouldn't work after that.

What's wrong with having an earth elemental doing it? It's under his control. He is a fucking mage, after all.

That means less than you seem to think. |

You mean he has less control over the elemental than I think?

ah, directional antennas and all that. i kinda recall a thread or 10 about that when it was anounced that SR4 would have a wireless matrix. |

Keep in mind that RFID tags only have a range of 3 meters. This is less than desirable for "tracking" runners who run through all sorts of matrix dead zones, or zones with less than desirable coverage. Frankly, RFID tags shouldn't even have a range that large. An RFID tag costs 1/20 of a nuyen. Even a security tag costs only 5 nuyen. Less than a half-eaten soyburger. That doesn't buy you very much. Look at the costs for other signal rated devices.
As for essense, the RFID section states that security tag implantation takes no essense. |

I think this is more attesting to the 2070's ability to sort out RF noise from data using q-physics. :D |

Keep in mind, passive tags are powered only by the radio waves from the reader. That's not much power for emission. Hence, ranges should be smaller. |

Where do they max out? That is, if your reader was pushing out a *lot* of power, would the range get noticeably larger?

Read Kiedo and Hobgoblin's statments about directional anntenna: 67 feet with signal distortion is the record for passive.

Actually, I can't believe 67 feet is right. sounds a little weak ... when I have time, I will look into it, somehow I think it is much more than that.

It may affect the range, somewhat, but the size of the tag is also a factor. For instance, the 12mm x 2mm passive chip has an effective range of between 0.75" and 1.5", depending on angle, pretty much regardless of the volume the reader's throwing at it. The 8mm x 2mm have even less. So a super-reader charging the chip as much as possible may increase the range by .01 or .02 inches. |

Standard readers aren't designed to pick up the response except at close range but if I fire up a 50,000W RF emitter on the RFID frequency, there will be trillions of those little buggers chirping like mad. The trick is having an antenna in the right location that is sensitive enough to hear the responses. Angle of incidence & antenna sensitivity is probably the big limiter on the effective range b/c building an RF emitter is almost trivial.
Your RFID's security is essentially reliant upon the laziness and disinterest of the rest of the world. I'm positive that if RFID chips in the hand become even vaguely common, someone will build an RFID scanner into a glove, watch and/or ring. |

hmm, did i link to a wired article where someone had basicly palmed the external antenna of a rfid reader and put the rest of said reader up his sleeve?
and why bother to build an antenna into a piece of clothing? your carrying around a rfid reader in your comlink... |

Well, that about makes it perfectly secure. |

This is an unfair comparison. I'm using my RFID tag for stuff like keyless entry, some limited home automation, and logging into my PC. I can't imagine anyone going through all the trouble of finding and stashing a compatible reader, clandestinely scanning my hand, cloning a tag, and then using it when they could just kick in the door when I'm at work. I don't own anything anyone willing and able to hack my tag's code would want. Consequently, for the time being, I am pretty much completely secure. |

*shrug* You're about as secure as people who leave their doors unlocked because they live in a good neighborhood. All it takes is some yahoo realizing that the doors in that neighborhood are unlocked, and in he'll go.
Fair enough. It's more the future I'm looking towards. If the only things your RFID is linked to are stuff like opening the door to your house, then there's easier ways of stealing anything that you've got than trying to rip it off using your RFID. It's the SR scenario, where your RFID and commlink are pretty much the same as your signature and thumbprint on everything from doors into buildings to accessing your bank account, that you'll find criminals developing an interest in snatching RFID info secretly. |

I've just recently discovered the Discovery Channel show "It Takes a Thief." The things that make you think you're secure aren't really all that helpful. On yesterday's episode the guy climbed through the front window of a house on a busy New York street and nobody saw or cared.

That's the nice thing about telecommuting... you're your own security guard.
Just need a pistol under the desk. |
