Collaborate Disseminate
Hackaday editors Elliot Williams and Mike Szczys check in on the best hacks from the past week. All the buzz is the algorithm that can reverse engineer your house keys from the way they sound going into the lock. Cardboard construction goes extreme with an RC car build that’s beyond …read more
Near-field Communication (NFC) has been around a while and is used for example in access control, small data exchange, and of course in mobile payment systems. With such sensitive application areas, security is naturally a crucial element of the protocol, and therefore any lower-level access is usually heavily restricted and …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
So I have a small electronics project where I am using common Mifare Classic 1K NFC tags as a means of authentication. (Mifare DesiFire is just too expensive)
I know these aren’t very secure so here are my ideas on improving on it.
Make C… Continue reading Hardening NFC tags for authentication
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.
Th… Continue reading Detect card type (RFID, NFC, Magnetic, …) [duplicate]
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]
Waveshare, know for e-ink components aimed at hobbyists among other cool parts, has recently released a very interesting addition to their product line. This is an enclosed e-ink display which gets updated over a wireless NFC connection. By that description, nothing head-turning, but the kicker is that there is no …read more
