Though kids today have an incredible knack for figuring out modern phones and tablets, there’s still something to be said for offering a simple physical user interface for little hands. To that end, [Martin Hierholzer] has put together a whimsical …read more

It’s known that card readers, which use the Wiegand format, can be attacked by installing a sniffer, such as an ESPKey. After the sniffer is installed, whenever anyone uses the reader, their credentials get saved, and the attacker can clon… Continue reading Defending against Wiegand sniffing (ESPKey) attacks in RFID card readers
The title is pretty self explanatory. The market is pretty secretive about these kinds of matter since companies won’t give out vulnerabilities for attackers to abuse and will give out vulnerabilities that are solved and attackers would th… Continue reading Are there any contactless (RFID/NFC) card vulnerabilities that are still unsolved? even minor ones
Feel free to correct my below logic.
As far as I can tell, HF RFID tags (specifically I’ve tested MiFare Classic 1kb) have a 48-bit encryption key (default to 0xFFFFFFFFFFFF or something) to protect their contents. A quick Arduino RFID rea… Continue reading Does UHF RFID implement any security at all?
I’m new to RFID blocking and find it interesting. I came across this video to learn more and just have 2 questions

Why would Vaultcard (4:42-5:30) protect both sides while Antetoko (8:47-9:20) pr… Continue reading What are the different types of RFID shields for cards? (Some seem to block 1 side only, some affects all nearby cards regardless of side, etc.)
[ananords] and his girlfriend wanted to make a simple and easy to use music player for her grandmother. Music players like CD players and MP3s have gotten just a bit too difficult to handle, so they wanted to find a much simpler solution.
They conceived the idea of creating a …read more

Microwaves used to be simple to use. Set the dial for the desired time, and hit start. Then, everything went digital and the average microwave now takes between four and six button presses in precise order just to start heating. Music players have gone down a similar path, and those …read more
We are evaluating how to improve security on our RFID System. Our system was reviewed by someone finding the point that there are duplicate Tags we must get rid of.
So the first idea was to read the UID to ensure that the used tag is not a… Continue reading RFID // Understanding security of Standard-UID
We are continuously inspired by our readers which is why we share what we love, and that inspiration flows both ways. [jetpilot305] connected a Rothult unit to the Arduino IDE in response to Ripping up a Rothult. Consider us flattered. There are several factors at play here. One, the …read more
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.
Th… Continue reading Detect card type (RFID, NFC, Magnetic, …) [duplicate]
