Arduino time attendance system with RFID

A how-to on building a time attendance system with MFRC522 RFID Reader and Arduino from Random Nerd Tutorials: Before getting started it’s important to layout the project main features: *It contains an RFID reader that reads RFID tags; *Our setup has a real time clock module to keep track of time; *When the RFID reader reads an […]

Inside a RFID race timing chip: die photos of the Monza R6

Ken Shirriff took some die photos of the Monza R6 chip  and wrote a post on his blog on how the RFID timing chip works: I recently watched a cross-country running race that used a digital timing system, so I investigated how the RFID timing chip works. Each runner wears a race bib like the […]

Automatic feeder mod makes cat work for food

Here’s a cool automatic feeder for your cat that dispense food in exchange for a wiffle ball by Benjamin Millam.  He wrote a post on his blog detailing its assembly: I used an Adafruit RFID reader to detect RFID tags embedded in the wiffle balls: the balls are cut slightly, enough to slip in an […]

American pro football using RFID

With the start of the USA’s pro football season the NFL has announced the use of RFID technology to enhance reporting of player performance data. The NFL partnered with Zebra Technologies, which is applying the same radio-frequency identification (RFID) technology that it has used the past 15 years to monitor everything from supplies on automotive […]

RFID reader for BuildBrighton door pt II

Chris Holden has written an article on their new door entry system at BuildBrighton: The basic idea is this: A keyfob is presented to the reader and the serial number read from it. The keyfob number is displayed on the character LCD. This is sent (via the ethernet module) to a URL to validate the serial number […]

30c3 video: hacking RFID public access control systems

In this video from the 30th Chaos Communications Congress, Adrian Dabrowski lectured on RFID based access control systems which are becoming common in Europe. These systems debuted in 2006 and use RFID cards as a substitute for a previous mechanical key system to allow emergency service, delivery and other personnel unassisted access to the common […]

Dissertation: security analysis of contactless payment cards

Here’s an interesting academic document we found related to hardware hacking. In this published doctoral dissertation, Timo Kasper from the Ruhr-University Bochum, Germany, presents in detail his efforts in analyzing the security of Mifare smart cards. “The tools are first employed for analyzing a contactless payment application, which is based on Mifare Classic technology, with […]

A stand-alone access control with RFID

Boris of Open Electronics wrote an article on his stand-alone access control with RFID project: RFID Tags are increasingly used for many applications such as identifying objects by means of a code or access control. In logistics RFIDs allows asset tracking, or monitoring conveyor belts; in shops tags are often used as anti theft. RFIDs are […]

DEFCON video: Live Free or RFID Hard

In this talk from the 2013 DEFCON conference, Francis Brown and Bishop Fox provide practical insight into how RFID proximity badge systems work. They highlight the real world difficulties encountered in reading RFID prox cards with conventional readers, and what you’ll need to build out your own RFID physical penetration toolkit. They use an Arduino […]

Open source RFID evaluation tools

A group from the University of Oulu (Finland) has developed and released a set of open source tools for auditing RFID signals. They describe, We have provided in this toolkit a systematic analysis for the RF protocol of RFID systems. The tools are either written for the Gnuradio software and the USRP software radio hardware […]

RFID Multipass spoof using ATTiny85

Hudson from NYC Resistor was inspired by Beth’s avrfid.S project to try to build a replacement for the multiple HID Prox card he carried for work. Hudson notes that “Beth’s design is simultaneously a technical tour-de-force and an example of how badly we can abuse the Atmel chips.” The entire schematic consists of an ATTiny85 […]

OpenBeacon – An open source active RFID project

OpenBeacon is a comprehensive open source platform for active RFID applications operating in the license free 2.4GHz ISM band. The project involves base station hardware, as well as active tag hardware. OpenBeacon is based on Open Source software and a very flexible and reprogrammable lowcost Open Source RFmodule. The firmware sources and hardware schematics are […]

STM M24LR04E-R 4-Kbit dual interface EEPROM with RFID

STMicroelectronics has introduced the M24LR04E-R 4-Kbit Dual Interface EEPROM with RFID. “The M24LR04E-R device is a dual-interface, electrically erasable programmable memory (EEPROM). It features an I2C interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The M24LR04E-R is organized as 512 […]
