Reverse engineering the crypto in an RFID tag

Reverse engineering the crypto in an RFID tag

Sunday, August 2nd, 2009

This was posted on RFID Toys a little over six months ago, but I was just cleaning files from my cluttered laptop and re-discovered this gem. These guys over at the University of Virginia reverse engineered an RFID tag by physically shaving down the chip to reveal transistor layer after transistor layer, taking images of […]

Email from a friend concerned about RFID enabled passports

Monday, July 20th, 2009

I recently received an email from a friend who wanted to get the low down on RFID enabled passports. She had received the following suggestion from another source: Some scary possibilities for identity theft are present with the technology chosen for new American passports – all newly issued American passports have it. A brief Google […]

Review of Ananiah Electronics RF9315R active RFID reader with RSSI

Review of Ananiah Electronics RF9315R active RFID reader with RSSI

Wednesday, July 1st, 2009

A while back I did a review of some of Ananiah Electronics‘ RFID modules and readers. These are simple RF devices that fulfill the baseline requirement of an RFID device (periodically transmits an identifier)… but the great thing about these modules is the price. You can get them for a steal of a deal, which […]

Stamp based security system

Stamp based security system

Sunday, May 31st, 2009

I’m working on a project that involves green computing, and oddly enough an old building. This project has a low budget at the moment, but still requires a flexible security system for an inner and outer door. I figured I could easily put a BS2 chip to the task and come out with a pretty […]

A series of observations

A series of observations

Sunday, May 3rd, 2009

I’ve taken to using my trusty camera phone to quickly snap things I find interesting or noteworthy, if only to me. Over the last couple days I had several opportunities. First off, we woke up early to take a morning walk and passed this guy’s car. He’s obviously just as tired of the lipper traffic […]

Friday, April 17th, 2009

The free bonus chapter I have available for download shows people how to build a basic RFID based access control system for your front door. In it, I detail how to take a PowerBolt electronic pin code deadbolt and add RFID as an alternative authentication method. Well the people that make the PowerBolt electronic deadbolt […]

Can you sterilize an EM4102 tag in an autoclave?

Review of DataSafe security wallet

Review of DataSafe security wallet

Sunday, March 22nd, 2009

In a fit of frustration the other day, I broke my wallet by slamming it down on my desk. The frayed edges of my trusty old wallet couldn’t take the strain, and my credit cards, loyalty cards, and RFID cards ripped through the frail seams and went flying all over the place. The deflated little […]

Effect of thumb flexion / extension on RFID implant range

Saturday, March 21st, 2009

I wanted to post this video to show just how the body’s own tissue interferes with an RFID implant’s ability to be read, even with a high power reader. These tags have very low read range due to their size, and the location I chose between the thumb and index finger of the hand offers […]
