Why is that no longer a concern?
I would certainly be concerned about it.
Even if the cards can't be cloned from a distance, couldn't they still be tracked from a distance? Could the school actually be helping stalkers follow students unobtrusively?
- TeMPOraL 14y agoIt is, and the cards still can be cloned. You just need a big enough antenna. See: http://hackaday.com/2012/05/27/reading-rfid-cards-from-afar-easily/ http://hackaday.com/2012/05/27/reading-rfid-cards-from-afar-... + I recall someone else building a big antenna that allowed to read cards from range of meters.
- Wingman4l7 14y agoReminds me of the "bluesniper", which was basically a Yagi antenna on a rifle stock, meant for sniffing Bluetooth devices from a distance.
- cbhl 14y agoIt's debatable. Some steps have been taken to mitigate the impact (foil envelopes for your Passport Card, basic shielding on e-Passports, the introduction of MiFare DESFire as an alternative to MiFare Classic) but AFAICT it's still possible to skim the cards remotely. There was a period of time when these concerns were all over mainstream media (especially in Canada and Europe, during the migration to Chip-and-PIN, particularly for credit cards) but you don't see it often these days (except in extreme cases like the one in this article).
