A massive increase in international co-operation and significant investment in awareness-building and training are essential if the concept of an Internet of Things (IoT) is to be turned into a meaningful reality, says a European Union-funded project in its final report, “RFID and the Inclusive Model for the Internet of Things.”

Bokode: Imperceptible Visual Tags for

Camera Based Interaction from a Distance

the contemporary hybrid city through the lenses of my research work augmented by some offline observations. In this intervention entitled “People as sensors; people as actors” (slides with annotations), I look at the integration of ubiquitous technologies (and soft infrastructures) and how they afford us new flexibility in conducting our daily activities (people as actors) with simultaneously providing the means to study our activities in time and space (people as sensors).

This tutorial introduces a Processing interface sketch provides a GUI for the command-line interface written into the Arduino RFID example. You should read that tutorial first. The sketch shown here also allows you to upload tags it reads to O’Reilly’s Emerging Technology Conference attendee portal, and retrieves the resulting profile. The API for this was written by Edd Dumbill. The Processing sketch retrieves RFID tags from the Arduino reader serially, then passes the tag via a HTTP request to a PHP script on a remote server, shown below, that adds an authorized login to the O’Reilly site.

This tutorial shows how to make an Arduino-based RFID reader that reads Mifare tags and stores them in EEPROM. It is a modification of Alex Zivanovic’s code on Tinker.it. Thanks to Alex and Massimo Banzi for the reference. Once you’ve got it running, go on to the RFID to Web example, which provides a Processing interface sketch provides a GUI for the command-line interface written into the Arduino code.

Mifare RFID tags, like other RFID tags, contain a serial number that can be read using an RFID reader, but they also have a limited amount of memory space that you can write data to, and read back from. This can be handy if you want to do something like keep a user’s account balance or name directly on the RFID tag.

This tutorial explains how to read from Mifare RFID tags from your computer using a Sonmicro SM130 read/write module. The sketch below is written in Processing using my SonmicroReader library. The SM130 has a TTL serial interface that you can connect to a micocontroller, or to a personal computer through a USB-to-serial interface. Using the latter, it’s pretty simple to send serial commands to it and receive the data back. The entire Processing sketch can be downloaded here: rfid_simple_0001.

Sonmicro RFID Reader Library for Processing

libnfc is the first free NFC SDK released under the GNU General Public License which provides complete transparency and royalty-free use for everyone. Since the RFID market is spoiled by proprietary hard and software we want to contribute constructively by distributing a free library which can be used for various RFID and NFC applications.

Using simple abstractions such as the dashed line and the kinds of visual language that we have previously proposed for RFID allow us to quickly communicate aspects such as the spatial properties of wireless technologies that are often overlooked. I’ve been using these images in presentations for a while, to sensitise designers and students to the spatial and embodied properties of RFID, Bluetooth and WIFI.

The RFID sniffer is a simple analog electronic circuit which can detect the presence of 13.56 MHz RFID tags. These tags are commonly used in all kinds of plastic cards like access badges, bank cards, library cards, loyalty cards and so on. Also many other objects may carry RFID tags without you knowing it. Books, toys, and even clothing might be tagged. Carrying tagged objects with you can reveal your identity or whereabouts to anyone equipped with the appropiate tools to read RFID tags.

Mediamatic organizes two RFID Sniffer workshops. On Friday March 27 or on Saturday April 4 you can assemble your own RFID Sniffer circuit, guided by the Sniffer designer Marc Boon
