On Relaying NFC Payment Transactions using Android devicescgvwzq
NFC (Near Field Communication) defines the set of RFID standards designed to bidirectionally communicate via wireless and interchange data point-to-point between devices in proximity, normally a few centimeters (up to 10cm). Services that use NFC communications as contactless payments are exponentially growing: Public transport, parkings, fast supermarket cashers, vending machines and even NFC-capable credit/debit cards.In this talk, we investigate relay attacks in NFC-capable credit/debit cards. This attack exploits the communication proximity principle in NFC, which is shown to be non secure. Although a lot of attack countermeasures exist, they do not face with this attack vector since up to date special hardware was required to perform it. However, the story is rewritten with the NFC-capable mobile devices available in the market.
This work shows how nowadays a relay attack in NFC-capable credit/debit cards is possible using an NFC-capable Android device without further modifications (i.e., no root permissions, custom firmware, or custom OS are required). A PoC app implementing the attack is shown in the talk, as well as distributed relay attack scenarios that might become real before long.
Transit Ticketing and Fare Collection Conference - Introduction to the Intero...NFC Forum
This presentation was delivered at the Transit Ticketing and Fare Collection Conference by Dr. Joerg Schmidt, 1st Co-Chair Transport SIG, NFC Forum
Key presentation take-aways include:
- RF interoperability with mobile Public Transport services is a reality
- All certified NFC-enabled mobile devices will work with Public Transport systems
- NFC Forum leads interoperability efforts
For latest developments: www.nfc-forum.org
NFC is based on a short-range wireless connectivity, designed for simple and safe interaction between electronic devices. It is easy to use wireless communication interface for last few centimetres . Connection between two devices is established just by holding the devices close to each other or touch them together.
NFC traces its roots back to radio-frequency identification, or RFID. RFID allows a reader to send radio waves to a passive electronic tag for identification, authentication and tracking.
2004 Nokia, Philips and Sony established the Near Field Communication (NFC) Forum.
2006 Initial specifications for NFC Tags.
2006 Nokia 6131 was the first NFC phone.
2009 In January, NFC Forum released Peer-to-Peer standards to transfer contact, URL, initiate Bluetooth, etc.
2010 Samsung Nexus S: First Android NFC phone shown.
2013 Samsung and Visa announce major partnership to develop mobile payments
NFC was approved as an ISO/IEC standard on December 8, 2003 and later as an ECMA standard.
ISO/IEC 18092 / ECMA-340 - Near Field Communication Interface and Protocol-1 (NFCIP).
ISO/IEC 21481 / ECMA-352 - Near Field Communication Interface and Protocol-2 (NFCIP-2).
NFC incorporates a variety of existing standards including ISO/IEC 14443.
In addition, the NFC Forum has defined a common data format called NFC Data Exchange Format (NDEF).
As with proximity card technology, near-field communication uses magnetic induction between two loop antennas located within each other's near field, effectively forming an air-core transformer.
NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target.
This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries.
NFC peer-to-peer communication is possible, provided both devices are powered.
Most of the RF energy is concentrated in the allowed ±7 kHz bandwidth range, but the full spectral envelope may be as wide as 1.8 MHz when using ASK modulation
NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less.
NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s.
It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz.
Theoretical working distance with compact standard antennas: up to 20 cm (practical working distance of about 4 cm).
Supported data rates: 106, 212 or 424 kbit/s (the bit rate 848 kbit/s is not compliant with the standard ISO/IEC 18092).
NFC devices are able to receive and transmit data at the same time.
The 'digital wallet' exists in the cloud, and it is not tethered to one specific device such as a mobile phone, but accessible from a variety of devices such as laptop, iPad, ultrabook or even Xbox.

Advantages& Disadvantages of NFC
Conclusion
Near Field Communication or NFC, is a short-range high-frequency wireless communication technology which enables the exchange of data between devices over about a 10centimeter (around 4 inches) distance. NFC is an integration of Radio Frequency Identification (RFID) technology with mobile devices. The technology is a simple extension of the ISO 14443 proximity-card standard (contactless card, RFID) that combines the interface of a smartcard and a reader into a single device. NFC operates at 13.56MHz and has 424kbps maximum data transfer rate. NFC technology is being grown up at enormous speed as it provides the fastest way to communicate between two devices within a fraction of the second. Also, NFC offers a quick and convenient method of interaction between humans and NFC enabled devices. An NFC device can communicate with both existing ISO 14443 smartcards and readers, as well as with other NFC devices, and is thereby compatible with existing contactless infrastructure already in use for public transportation and payment. This technology has only been implemented on smartphones so far. Near-field Communication is characterized as a very short-range radio communication technology with a lot of potentials, especially when applied to mobile handsets. Usage of NFC includes the electronic wallet to make payments using the handset, the same way as credit cards. Several security issues are attached with NFC, which is a big concern. Security attacks like eavesdropping, data corruption and modification, interference attacks and theft, are the most dangerous for the customer who is using his/her smartphone for payment purpose.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

NFC or Near field Communication is the technology of future which is
capable of transforming our lives. It is capable of making our life so easy
and comfortable to level never thought before.
Advances in this field and no need for the new infrastructure for this
technology in this event pave the way to the motto for NFC that sees it as
NFC EVERYWHERE
4. What is NFC?
4
Near Field Communication, the tap-and-go technology co-invented by
NXP more than ten years ago, has shifted into high gear.
This simple, intuitive technology, which lets you initiate interactions with a
simple touch, is now in millions of smart phones, tablets, and other
consumer electronics, with new devices arriving almost daily.
NFC is a technology for contactless short-
range communication .
To begin with
•It’s a proximity technology
•Eavesdropping is a near impossibility
• NFC is unique in the way it uses energy
5. Technical Overview
5
The term field is the radiations radiated by the antenna. As name suggests
NEAR FIELDS so its clear that the fields that are in closed vicinity of the
antenna are Near Fields and these are used for NFC.
NFC communicates via magnetic field induction, where two loop antennas
are located within each other's near field, effectively forming an air-core
transformer.
•Frequency of operation is 13.56 MHz
• Working distance with compact standard antennas: up to 20 cm
•Supported data rates: 106, 212, or 424 Kbit/s .
8. Technical Overview
8
Communication Modes
Read/write Mode
In Read/Write Mode, the system performs the functions of a contactless
reader/writer. The system’s NFC interacts with an NFC-enabled device and
either reads data in from the device or writes data out to it.
Power savings
Works in Passive Mode therefore no need of power source for target. It will
act on the power provided by the initiator.
Secure transactions
To increase the security of Read/Write Mode, a Secure Access Module (SAM),
can be used to encrypt data. It verifies your data thus acting doing double
check.
9. Technical Overview
9
Communication Modes
Peer to Peer Mode
It is used to establish a two-way communication channel between a pair of NFC
enabled devices. Each NFC-enabled can initiate a communication as equals, or
peers. This mode uses either a passive or active communication scheme.
Two-way interactions
Pairing with Bluetooth or Wi-Fi, exchange business cards with a colleague, or
receive frequent-flyer points when purchasing an airline ticket is possible.
Power savings
Peer-to-Peer Mode can use a passive communication scheme. Only one device
needs to be active, drawing power to generate the necessary RF field.
10. Technical Overview
10
Communication Modes
Card Emulation Mode
This mode lets the system behave as an compliant contactless smartcard. This
means that the NFC-enabled device can be used in the existing contactless card
infrastructure, for things like ticketing, access control, contactless payments etc.
Power savings
Card Emulation Mode saves power by using passive communication. In this
mode, the smartcard or NFC device modulates the RF field generated by the
initiator of the transaction, which is likely to be a contactless reader in a
building-access or payment application. This results in very long lifetime in the
field.
12. Where NFC stands In World?

13. Where NFC stands In World?
13
NFC v/s RFID
NFC and RFID, both the technologies are for short range. NFC can be referred
as the advance version of RFID as it is having few additional features compared
to RFID.
Range of RFID is less than 40m and frequency of operation vary depending
upon the application. Frequency may vary from LF (120 to 150 kHz), HF (13.56
MHz) and UHF(433 to 900 MHz).
NFC is having compatibilty with the RFID system infrastructure and in addition
enable peer to peer mode that in fact makes data transfer possible between
two devices.
RFID technology can be replaced by NFC in many fields like door locking etc but
not in all especially in logistics and retails due to its low cost.
15. NFC Application
15
NFC for Access
Conventional keys can be copied inexpensively at corner shops, and
research into 3D printing shows how easy it could soon be to replicate
even sophisticated high-security metal keys. NFC key can provide high
security level with its ease to carry.
