Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into proximity, usually no more than a few inches.
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.

Near Field Communications - NFC - Uses, Applications, Cost and Much MorePraful Manjunath
Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other.

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.
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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
