I am trying to design an authentication system that will be based on NFC Ultralight C cards.
Key concept in my system is that the card identifies a specific person, but this concept can be easily broken if the card can be cloned.
I want to… Continue reading NFC Ultralight C – design an authentication system (can it be clone protected?)
I would like to know how the communication between my gym card and the checking point works.
I bought an ACR122U reader, but it seems that I can’t read my card with it, the card is not recognized as something readable with that adapter.

E-paper displays are unusual in that power is only needed during a screen update. Once the display’s contents have been set, no power whatsoever is required to maintain the image. That’s pretty nifty. By making the display driver board communicate wirelessly over near-field communication (NFC) — which also provides a …read more

I am building E-Passport readers for the NFC chip they have, the main problem I have is that there are differences between the passports from each country.
That is why I need passport specimens.
I know they are distributed somehow. I own a… Continue reading Getting Passport specimens [closed]

OpenSK is a piece of firmware that you can install on a USB dongle of your own, turning it into a usable FIDO or U2F key. Continue reading Google launches open-source security key project, OpenSK
If home automation in the IoT era has taught us anything, it is that no one wants to run wires. Many of us rent, so new cabling is not even an option, even if we wanted to go that route. If you want a unique sensor, you have to build …read more
When [gdarchen] wanted to read some NFC tags, he went through several iterations. First, he tried an Electron application, and then a client-server architecture. But his final iteration was to make a standalone reader with an Arduino and use WebUSB to connect to the application on the PC.
This sounds …read more
I am trying to copy some NFC card; however the SAK returned is always 08h using the command nfc-list. However looking through the actual content of the card, I can see that the byte associated to the SAK is different (88h).
