Nokia recently announced that it would release an RFID reader that can be attached to its cell phones. Currently it's envisioned as a tool for service technicians and other mobile workers. As MobileMag reports (or just picks up from the Nokia press release-- much the same language appears in articles in vnunet and edubourse),
The Nokia Mobile RFID Kit extends the mobility of field force personnel by integrating RFID reader technology to a familiar portable device. Simply by touching a smart object, the user can initiate tasks in their Nokia phone - call and send text messages or access databases and record new data entries.
"There are numerous ways to utilize the Nokia Mobile RFID Kit in a business", said Gerhard Romen, Head of Market Development, Nokia Ventures Organization. "The user can easily launch services and conveniently access phone functions like dial or send messages, just by touching smart objects, in this case RFID tags. The phone reader will read the content of the smart object, and translate it to an action. For example, a field service engineer can intuitively start browsing the latest service instructions to repair a machine on site. It is also possible to collect meter reading data to the phone by keying the reading into the phone, replacing the paper and pen method still widely in use today. The Kit can also replace the pen and paper method in recording time and attendance, for example."...
The Nokia Mobile RFID Kit is an enabler of Nokia's "Life Goes Mobile" vision in making mobile phones more intuitive for users. Touching a smart object with a mobile phone is an easy way to connect to mobile services and content. It will not only improve the experience of using current services, but also create entirely new applications and value.
As Peter Winer
notes, there's an interesting potential consumer use of this kind of technology: "Conceptually, empowering consumers with their own handheld readers counterbalance some privacy concerns related to RFID. Presumably consumers could use the reader to detect tags present and act accordingly." This particular version has a very limited range-- which makes sense for applications in which you know where the chip is, and want to retrieve information from it (as in the repairman example), rather than determine whether or not you're tagged-- but the principle is intriguing.
(My own sense from talking to people working with RFID-- and granted, I've only spoken to people who are in large, publicity-conscious companies, not edgier (or more morally suspect) ones-- is that the secret tag scenario is not one we need to worry too much about. In order to use tags to monitor someone's movements, you also need to set up detectors in lots of different places. In constrained spaces-- like shopping malls, for example-- this might be feasible, but in larger, more open spaces, you're not likely to get better results than if you used videocameras; and for now at least, RFID would not be the technology of choice for tracking someone as they go about their day. For both technical reasons, and because of vigilance on the part of consumers and privacy advocates, Mark Roberti is probably right that it's "highly unlikely... that companies will be able to get away with using RFID data to track individuals without their consent.")
But if you wanted to give people the ability to guard against RFID-enabled intrusive uses or monitoring, detecting secret tags would be half of the equation; the other half would be detecting unexpected attempts to interrogate tags-- not to secretly plant tags, but to secretly read them. This would require little more than a sensor-- essentially an RFID tag with a bigger-than-normal antenna and a little extra electronics-- that could alert users when they're in the presence of a reader. Today, they might be the size of a postcard; eventually it could probably be pendant- or coin-sized. If it went off near a checkout stand, no big surprise; but if it went off in an unexpected place, you might ask questions.
More generally, I think one thing we're going to see in the next couple years are the developement of relatively cheap technologies that give consumers the ability to tell when RFID tags are being read, and whether they're embedded in a product. These won't have to be expensive, and as the Nokia case shows, they could even be integrated into devices we already carry around. One doesn't want to rely exclusively on technological fixes for privacy issues, but it is worth recognizing that such tools could be developed, and could be used by consumers to monitor whether someone is trying to do something illicit or unexpected.
