NFC allows contactless communication between devices within 10 cm of each other. It uses magnetic field induction to transfer data wirelessly. NFC is commonly used for contactless payments and data sharing by tapping two NFC-enabled phones together. The first NFC phone was released in 2006, and it is now used in many smartphones and IoT devices for applications like mobile payments, ticketing, and device pairing. While convenient, NFC has limitations including a short range and low data transfer speeds. It also poses privacy and security risks if sensitive data is intercepted.

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 is wireless technology which provides communication between two mobile phones which
contain NFC tags, using short range radio waves. It uses the magnetic field induction for this purpose. Both devices can communicate with each other using NFC technology when they touch each other or brought very close to each other. It requires short range of approximately ten centimeters to perform the exchange of information between two devices.
We can do payment using our NFC enabled phone by swiping it out in front of the phone reader and then the purchase price will automatically paid from credit card or debit card. Our mobile phone can be used in place of wallet, credit cards, debit cards etc. We don’t need to carry our credit card or debit card with us. But with these advantages, we will have to face disadvantages too. There are some security threats to NFC technology, which should be prevented.
NFC technology uses RFID (Radio Frequency Identification) for data/information exchange between two devices over a short distance like Bluetooth and Wi-Fi technology. NFC enabled smartphone users can make transactions and access information with only a simple touch. NFC devices can send and receive data simultaneously. So this technology has a very bright future scope. Since it is a new technology, so NFC enabled mobile users need to be educated on how it will work for them to make payment or exchange any information. But there is a requirement of a protected infrastructure for NFC technology so that it could be widely adopted all over the world. This technology has several advantages over other wireless technology because it provides bidirectional communication for exchanging information.
For example if someone have a laptop and cell phone equipped with NFC, then he/she can easily download data from Internet into the cell phone by simply touching
the cell phone with laptop. Like that you may take pictures by the cell phone and if you want to show those pictures to your friends on big screen then you may just touch your phone with TV and show them. Or if you want to print those pictures then by touching the cell phone with NFC equipped printer will give you the prints of those pictures. This principle works with any kind of
devices equipped with NFC to communicate with each other.
It’s operating frequency is 13.56MHz. Working distance with compact standard antennas is up to 10 cm. The rate of transfer of data is around 106 to 424 Kbit/s. For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag.
IR wireless is the use of wireless technology in devices or systems that convey data through infrared (IR) radiation. Infrared is electromagnetic energy at a wavelength or wavelengths somewhat longer than those of red light.

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.
