Experimenting NFC, things

Following my little NFC rants, I have kept on experimenting with Android NFC applications and reading about the Internet of Things (experimenting remains harder, here). The combination is trendy these days, as this week will see the launch of a new initiative in France with the French chapter of ACM SIGOPS (in French). I won’t […]


NFC Tags to Empower Users in The Internet of Everything Else

Here is a continuation to my ramblings about the solely private use of NFC tags. I have already mentioned that there would be many benefits in considering some tags as public goods, and now, I wll focus on tags to be associated to things, as owned by companies or individuals. I have pompously called this […]


NFC tags as Public Goods

I have now seen a number of NFC applications, and they all have something in common: they consider their tags as a private and exclusive property. They believe that they will be the only application using this tag. That may be true in some cases, where tags are deployed inside the premises of a company […]


POPWings again, after MWC

I now have two POPWings cards, as I made a new one with my professional contact information on Gemalto’s MWC booth yesterday. I also have had the ability to “pop” one or two persons, giving me a better experience of the application. So, I owe an apology to POPWings here. When I first tried their […]


POPWings is a cool business card, but where is the platform?

UPDATED March 1st, 2013: See follow-up article. I have been quite happy to hear a few weeks ago that Gemalto finally decided to consider NFC as more than secure services, by launching their POPWings service. I immediately ordered one of their business cards, excited to get a new NFC service. So, I got a card […]


RFID in schools, or Security vs. Transparency

I recently became enthusiastic about how wonderful transparent security would be. I still feel that way, but we also need to define limits on transparency. The example of a girl being expelled from her school because she refuses to wear a RFID badge (through @stoweboyd) is interesting. The issue is rather simple. A school has […]


Convenience vs. Security vs. (Perceived) Security

Yesterday, @poulpita tweeted a link to a blog explaining that convenience keeps winning against security. The main argument in this blog is about iOS6’s Passbook, which can store credit card numbers, for your convienience. The reasoning goes on with a comparison of the security merits of a credit card number stored on Passbook and a […]


JavaOne day 0: Strategy keynote

It’s Sunday afternoon in San Francisco, and time to get to work, after a nice bike ride. The first part has been the ride up Nob Hill to the Masonic Center, and that’s been hard. Once seated, we got a lot of news, but most of them not that new. Java ME 3.2, with its […]


Google sucks, or why it is nice to pay sometimes

I just spent two hours being upset at my daughter’s school, Google, American law, and a few more people. Let me tell the story. Two hours ago, my 12-year old daughter received an e-mail from her school inviting her to Google+. She accepted the invitation, and Google asked for her age. She told the truth, […]


Chip to Cloud, day 2: a key for the internet of things

This talk is by Pascal Urien, from Telecom ParisTech and Ethertrust. The talk is about keys, ranging from locks to electronic keys. The fisrt question is: are electronic keys a breakthrough application for the Internet of Things? Are people going to trust electronic keys to protect their physical goods? One of the starting points for […]
