Can Mifare Classic 1k be used for micro payments in a secure way?
I have a system in mind for use in a arcade game saloon. You are getting a card from cashier and can top it up for example with 100 points (they are written o… Continue reading mifare classic 1k for micropayments
With the arrival of Apple Pay and Samsung Pay in Russia, many are wondering just how secure these payment systems are, and how popular they are likely to become. In our opinion, these technologies require a more detailed examination and a separate evaluation of the threats they face. Continue reading Loop of Confidence
In the UK there has been a large increase recently in the use of contactless card payments (you pay by waving your card over a reader). Prior to this the primary way to pay with a card was to use “chip and PIN” where you inse… Continue reading Contactless credit cards security
Millions of NFC Mifare Classic cards are used for public transport, access control and other purposes. These NFC tags use encryption so that the data on NFC tag cannot be read or changed by someone who scans the tag without … Continue reading Can we capture security key used in an NFC connection for Mifare Classic?
I have an NFC/RFID keychain that looks pretty much like this one:
When I read it with an Android app called “Nfc Reader”, it shows me a specific ID (always the same) and it says that these technologies are used: IsoDep, NfcA, NdefFormat… Continue reading Is it possible to clone an NFC/RFID chip that uses IsoDep, NfcA and NdefFormatable
The report comprises two papers in which we analyze all existing methods of authentication used in ATMs and those expected to be used in the near future, including: contactless authentication through NFC, one-time password authentication and biometric authentication systems, as well as potential vectors of attacks using malware, through to network attacks and attacks on hardware components.

MIT Media Lab and Microsoft have teamed up to take wearable devices one step further — they’ve glued the devices directly to the user’s skin. DuoSkin is a temporary tattoo created with gold leaf. Metallic “Flash” temporary fashion tattoos have become quite popular recently, so this builds on the trend. What the team has done is to use them to create user interfaces for wearable electronic devices.
Generally speaking, gold leaf is incredibly fragile. In this process to yield the cleanest looking leaf the gold is not actually cut. Instead, the temporary tattoo film and backer are cut on a …read more

I’m reading about NFC and how its security can be enhanced. I read somewhere that it is possible to use TLS over NFC. Unfortunately, I can’t find any more information on that topic.
How does TLS over NFC works ? Is it someth… Continue reading How does TLS over NFC works?
Everywhere a question like this is asked, I see people responding that (in a scenario where a card is used) the card does some processing with the data it receives/generates some data when it receives a signal. How is this po… Continue reading How can RFID/NFC tags not be cloned when they are passive technology?
Near Field Communication (NFC) is something we take for granted these days. Nearly all smartphones have it. We even have NFC interfaces for all our favorite development boards. NFC’s history goes back all the way to 1997, when an early version was used in Star Wars special edition toys. Radio Frequency Identification (RFID), which NFC builds on, goes back even further. The patent citation trail leads all the way back to 1983 in a patent awarded to [Charles Walton]. NFC is much more than RFID though. The idea of two way communication between devices opens up tons of possibilities for …read more
