Tech Info Update 2023: All you need to know about NFC tags and stickers #drmobileslimited #nfc #virtualcard #businesscard #aucklandrepair

NFC (near field communication) is the technology that allows two devices — like your phone and a payments terminal — to talk to each other when they're close together. NFC is the technology that enables contactless payments.

Near Field Communication, known as NFC, may sound like a dry, technical specification. In many ways, it is. However, the applications of NFC are worth considering.
Android smartphones have had access to NFC for many years, while Apple's iPhones previously had a feature-limited version. However, both platforms use the wireless technology for contactless payments, headphone pairing, and some level of automation.

 
What is NFC?
Near Field Communication (NFC) allows wireless communication between two electronic devices close to each other. Officially, NFC can support distances of up to 1.5 inches apart, but it can be up to four inches in practice.

Generally, this comes in two forms; device-to-device communication or readable tags. While it is possible to make two devices interact via NFC, there are generally better methods of achieving this either through physical cables or other wireless technologies like Bluetooth or Wi-Fi.

That said, contactless payments are facilitated via NFC. So, when you walk into your local store and pay with your phone using Google Pay or Apple Pay, the transaction is initiated via NFC.

The primary interaction method, then, is between a device like a smartphone and a readable NFC tag. These tags are small, cheap, and unpowered. This is made possible because the reading device, often your smartphone, can generate a Radio Frequency (RF) field that will power the tag.

Can you use NFC stickers with an iPhone?
How to Use NFC on iPhone
Using NFC on iPhone is incredibly simple. All you need to do is bring your iPhone into close proximity with the NFC device or tag. To use NFC on iPhone: If you're using an iPhone XR or later, simply wake your iPhone to turn on the screen and Background Tag Reading will be enabled.

How do I use NFC on my iPhone 13 Pro Max?
From iPhone 12 to current iPhone 13, there is no need to turn on or off anything in control center (there is no setting actually) for NFC. Just hold your phone over an NFC Tag and your phone should automatically read it.

What can you do with NFC tags?

- Scan and names your NFC tag.

How long do NFC tags last?
10 plus years.  The NFC (near field communication) tag is made up of an antenna and a small passive IC chip usually on a PET substrate with an adhesive backing; no power source required. Tags have a lifespan of 10 plus years

What are the advantages and disadvantages of NFC tags?
NFC pros and cons. While NFC isn't free from security weaknesses, it's more difficult for hackers to access than many other types of RFID because NFC sends information through magnetic field induction, and the field fades faster. However, NFC's short range can be a disadvantage in various use cases.

Can a magnet erase an NFC tag?
No. NFC relies on alternating magnetic (and electrical fields) changing 13560000 times per second. A magnet represents a steady field, or at most one changing at the comparatively low rate at which you could physically move something. There will be no interference in terms of the actual signals.

Chat GPT update 2023: All The ChatGPT Updates To Know About #aucklandrepair #drmobilesnz #drmobileslimited #chatgpt

ChatGPT is what everyone is talking about right now. The artificial intelligence (AI) powered chatbot, created by OpenAI, has become the fastest-growing consumer application in history, crossing 100 million users in just two months. As the number of users continues to rise, OpenAI has been busy with introducing unique updates to make ChatGPT more accurate in its responses and factually robust.

The massive popularity of the chatbot has been indeed astonishing. According to a UBS study, the AI-powered chatbot clocked 13 million unique visitors per day in January. TikTok, one of the world's most famous social media apps, took around nine months from its launch to hit the 100 million mark in monthly active users. Meta-owned Instagram, which is almost every month coming up with new updates and features, took two-and-half years to reach the number.

Before we check out the updates, let's try to know what it is about this chatbot that makes it stand above the rest and challenge the authority and dominance of search engine behemoth Google.




Why is ChatGPT famous?

Users are turning to this tool for its obvious utility: it is an AI that can generate human-like responses to almost any question the user may have. The answer is often well-structured and loaded with precise details.

Built on Generative Pre-trained Transformer (GPT), ChatGPT is essentially a neural network learning model through which a machine can be trained to perform tasks that fall within the purview of natural language processing (NLP).

To put it simply, the GPT enables this new chatbot to respond in a conversational way, and the neural network is essentially a learning algorithm which makes the chatbots mimic the brain and understand human languages as they are spoken or typed.

Yet, despite all the hype surrounding it, this tool is still a work in progress.

Many have found problems with its answers, especially with regard to factual accuracy, since the information in it is limited to 2021. This means that the chatbot cannot give accurate answers to queries that would be connected to events after it, such as 'who won the FIFA World Cup 2022?' and similar questions.

Also, there are concerns over the manner in which it can be abused into giving answers it is programmed not to, such as generating ransomware or phishing emails — two of the biggest dark sides of the AI chatbot that researchers have been able to point at.

And, that's why updates become all the more important before it grows into the go-to search engine or digital assistant.

A dual-band Wi-Fi dongle is a small device that provides wireless connectivity to devices that don't have built-in Wi-Fi capabilities. It plugs into a USB port and allows the device to connect to Wi-Fi networks.

The term "dual-band" refers to the two frequency bands supported by the dongle: 2.4 GHz and 5 GHz. These frequency bands are used for wireless communication and have different characteristics.

The 2.4 GHz band is more common and widely supported. It provides good range and can penetrate through walls and obstacles easily. However, since it is widely used, it can be crowded and susceptible to interference from other devices like cordless phones, microwaves, and Bluetooth devices.

The 5 GHz band offers faster speeds and is less crowded, resulting in potentially better performance. It is especially useful in environments with many Wi-Fi networks or interference from other devices. However, its range is generally shorter compared to the 2.4 GHz band, and it may have more difficulty penetrating through walls.

By having a dual-band Wi-Fi dongle, you can connect to both 2.4 GHz and 5 GHz Wi-Fi networks. This allows you to take advantage of the benefits of each frequency band and choose the one that provides the best performance in your specific situation.
