What Exactly Is an NFC Tag?

Near Field Communication (NFC) is a wireless communication technology that allows two NFC-enabled devices to communicate using radio waves.

NFC for Android is available in recent smartphones, allowing users to easily share files and exchange data. However, NFC for iPhone is only available in IOS 11. (only iPhones 7 and newer are NFC-enabled).

NFC, on the other hand, only allows for short-range device communication. Two NFC-enabled devices must be approximately 4 inches apart in order to connect. This feature makes NFC transactions more secure and difficult for criminals to intercept.

Unlike RFID technology, NFC allows for two-way communication. This means that either of the two devices could serve as the reader or the tag. The smartphone that sends data serves as an NFC tag (it stores data), while the receiver serves as the reader.

The NFC tags are unpowered and are powered by another NFC-enabled device. When an NFC device sends radio waves, the reader's antenna activates and returns signals requiring data release. An NFC Tag's Components

An NFC tag is made up of three major parts: an NFC chip, a substrate, and an antenna. The following is a breakdown of each component's functions:

Chip NFC This microchip is very small (it is the smallest part of the NFC tag). It has memory, which stores information. It can store a variety of data, including images, email addresses, phone numbers, and website links. For ease of transmission, this data is stored in NDEF format (NFC data exchange format).

Antenna for NFC. This is the part of the NFC tag that detects and emits radio waves. It takes the form of a wire coil/loop etched on a strategic location on the NFC tag. If this component fails, communication will be impossible because no signals will be sent or received by the smartphones.

Substrate. This is the component that connects the NFC antenna and the NFC chip. It is the largest component of the NFC tag and, depending on the type of NFC tag, can be made of plastic or adhesive materials.

NFC tags come in different forms, including NFC stickers, NFC inlays, NFC labels, and NFC discs. This variety allows you to choose the format that best meets your needs. NFC stickers, for example, will be ideal for sticking on a work desk to automate tasks.

You can also purchase personalized NFC tags. NFC key fobs, wristbands, and mats, for example, are available.

How to Determine If Your Smartphone Is NFC-Enabled

If you're wondering how to check if your smartphone is NFC-enabled, simply follow these simple steps:

Navigate to the "Settings" menu on your smartphone.

Navigate to the section "Wireless and Networks."

Click "More."

If your phone supports NFC, the option will appear under "More."

Alternatively, open the "settings section" and use the search bar to look for NFC. If it returns NFC app results, your phone has NFC capability.

NFC Tags and How They Work

NFC tags operate in the same way that RFID tags do. They use radio waves to send data from one device (the tag) to another (the reader). Because they are primarily used to pass information in an automated format, these tags are also known as SMART tags or INFO tags.

It does not require pairing, making it a simple application process. All you need to do is bring two NFC-enabled devices together (approximately 4 inches). They will automatically connect.

Once connected, tap the files you want to share and choose NFC sharing. This way, you can share a large number of files at once!

NFC file sharing is more than ten times faster and more convenient than Bluetooth.

There are five main types of NFC tags.

You can buy five different types of NFC tags from your local NFC store. They are classified based on specific characteristics that influence functionality.

As a result, before purchasing an NFC tag, you should always define your requirements. This section will walk you through the five different types of NFC tags and their functions:

NFC Tags of Type 1

These are the most basic and slowest type of NFC tags. They store 93 bytes to 2 kilobytes of data and operate at approximately 106 Kbps (kilobits per second). This space is adequate for storing a URL or other brief information. However, the memory can be expanded to hold more information.

NFC type 1 tags are relatively inexpensive due to their simplicity. They may, however, lack the functionality required to automate various functions. These tags, for example, are read-only, making it difficult to write commands using NFC apps.

These NFC tags are primarily used in one-time provisioning, business cards, and reading a specific NFC tag when multiple tags are present. Here are some features that distinguish NFC tag type 1:

ISO 14443A standards are followed.

There is no data collision mechanism available.

comparatively inexpensive

You should only buy these NFC tags if you want to do simple tasks that do not require the transfer and storage of large amounts of data. While memory can be expanded, data transfer speed is slow and unreliable.

NFC Tag Type 2

A data collision protection mechanism is built into the NFC Type 2 tag. It has 48 to 144 bytes of storage memory (half of what Type 1 can hold). You can, however, increase the memory size to up to 2 kilobytes. It has the same communication speed as a Type 1 NFC tag (106 Kbps).

Type 2 tags, like Type 1 tags, operate in accordance with ISO 14443A standards. Ultralight, NXP Mifare, and Ultralight C are among the compliant products.

Overall, Type 2 NFC tags outperform Type 1 NFC tags in terms of functionality and speed. They are used for low-risk activities such as event ticketing, URL redirects, and low-value transactions.

NFC Tag of Type 3

These NFC tags cost more than both Type 1 and Type 2 tags. They adhere to ISO 18092 and JIS-X-6319-4 standards.

The tags have 1-9 kilobytes of memory and a speed of 212-2424 kbps. They also have an anti-collision feature, allowing you to use a single reader to read multiple tags at the same time. The Sony FeliCa tag is one of the products that has met all of the Type 3 tag requirements.

E-money, membership cards, electronic ID, transit ticketing, healthcare devices, home electronics, and e-ticketing are just a few of the applications for the tag.

NFC Tags of Type 4

These tags provide unrivaled adaptability. They operate in accordance with ISO-14443A standards and have memory capacities ranging from 4 Kb to 32 Kb. They have data transfer rates of 106/212/424 kilobits per second.

Furthermore, these NFC tags have anti-collision capabilities, allowing you to transfer data from multiple tags without signal collisions. NXP DESFire and NXP SmartMX-JCOP are two products that meet the Type 4 NFC tag requirements.

Unlike the other tags, Type 4 NFC tags provide a variety of data authentication methods. They support ISO 7816 security protocols and allow encoded content to be self-modified. As a result, you can use these tags with confidence.

The Type 4 tags are used in a variety of areas that require high security, such as payment and e-ticketing, due to their advanced security and memory features. The cost ranges from medium to high, depending on the features of the tag that you require.

NFC Tags of Type 5

The ISO/IEC 15693 standards are supported by these NFC tags. They are less expensive than Type 4 tags.

NFC Type 5 tags, like Type 1 tags, have a memory size of 192-3584 bytes and a processing speed of 106 kbps. It has an anti-collision system that allows you to use multiple tags at the same time.

NXP Mifare Classic 4K, NXP Mifare Classic 1K, and NXP Mifare Classic Mini are among the products that meet Type 5 requirements. These tags are used in inventory management in libraries, healthcare, and ticketing.

NFC tags of types 1, 2, and 3 can be rewritten (read and read/write options are available). As a result, you can obtain blank tags and rewrite information to meet your requirements (using NFC tag writing apps).

How to Select NFC Tag Chips

The NFC chip you select will be determined by your requirements. Before settling on your ideal NFC tag, consider the following NTAG features in addition to the types described above:

NTAG 213. These NFC chips are simple to use and dependable. They will meet the majority of your data transfer requirements.

NTAG 215. These NFC chips have a memory capacity of 540 bytes. They are ideal chips for bringing your Nintendo Amiibo tat home. These tags can be used to create amiibos from games such as Legend of Zelda and Breath of the Wild.

NTAG 216. These are high-quality standard chips ideal for NFC business cards. They can store a large amount of data and information.

Ultralight Mifare. These are low-cost chips that store simple data like URLs and ID numbers. They are ideal for high-volume projects with limited data capacity.

Always keep in mind that selecting the incorrect NFC type can be wasteful. If you want to make amiibos at home, for example, only NTAG 215 will work. Any other tag type will be a waste of money.
