Near Field Communication (NFC) is a set of communication protocols that enable data exchange between NFC-enabled devices. It uses NFC tags to store data that can be read and processed by an NFC reader.
NFC wristband is a type of NFC tag that can be worn on the wrist. It is typically used for event management, access control, and payment systems. We explain their popularity below.
What are NFC Wristbands?
NFC wristbands are your run-of-the-mill NFC tags designed in a convenient, wearable form factor. They come in all shapes and sizes but most commonly take the form of a bracelet or bangle.
NFC wristbands are made of different materials, including plastic, rubber, and silicone. They can be either disposable or reusable, depending on the application. They contain:
- NFC Chip. This is a 13.56 MHz contactless smart chip that stores data in NDEF format. It can be encoded with specific data such as an ID number, URL, or contact information.
- Antennae. This is a wire coil that powers the NFC chip and allows it to communicate with an NFC reader. The functionality of this part depends on the type of tag used. For example, antenna in active tags will continuously release signals while those in passive ones only release signals upon activation.
- Substrate. This is the material used to offer protection and support to the NFC chip and antennae. It must be hardy and durable.
NFC wristbands come in different sizes for children and adults. They can also be customized with company logos, colors, or other designs.
Uses of NFC Wristbands
- Contactless Payments
NFC uses 13.56 MHz radio waves to communicate between devices. This makes it perfect for short-range communication, such as mobile payments. It is accredited/approved by major credit card companies, meaning it is a secure way to make payments.
The NFC wristband can be used to streamline the checkout process. For example, if you are attending an event, you can use your NFC wristband to pay for food and drinks. This saves time as you do not have to carry around cash or a credit card.
But how does this work?
Well, these NFC wristbands contain an NFC chip that can be linked to your credit card/ bank account. When you tap the wristband on an NFC-enabled reader, it communicates with the reader and deducts the payment from your account.
This makes transactions quicker and more convenient for both customers and businesses. It has been estimated that contactless payments made with NFC will grow from $10 billion in 2020 to $17 billion by 2025.
- Event Management
NFC wristbands are often used for event management. They can be used to store information such as the ticket holder’s name, contact details, and emergency information.
This is extremely useful for large events where it is not possible to keep track of everyone manually. The wristbands can also be used to give attendees access to certain areas of the event, such as VIP areas.
This is done by programming the NFC tags on the wristbands with the appropriate access permissions. When the tag is tapped on an NFC reader, it will either grant or deny access to the person wearing the wristband.
There are many other ways that NFC wristbands can be used for event management. For example, they can be used for ticketing, managing queues, and collecting feedback.
- Access Control
NFC wristbands can also be used for access control. This is similar to event management but on a smaller scale. For example, an NFC wristband can be used to give employees access to a building or certain areas of a building.
NFC wristbands can also be used for hotel room keycards. This means that you can simply tap your wristband on the door to gain access to your room. This is much more convenient than carrying around a traditional keycard.
There are many other applications for NFC access control. For example, it can be used to give visitors access to a school or office building. It can also manage entry and exit at secure locations, such as data centers.
Why Everyone Love NFC Wristbands?
NFC wristbands have several advantages over other NFC tags, including:
- Comfort
NFC wristbands are designed for comfort, meaning you can wear them all day without experiencing any discomfort. This is not the case with other NFC tags, such as key fobs or stickers, which can be quite bulky and uncomfortable.
- Convenience
NFC wristbands are straightforward and convenient to use. All you need to do is tap them on an NFC reader, and they will automatically communicate with the reader.
When making payments, you do not need to enter your PIN or sign for the transaction. This makes NFC wristbands much faster and more convenient than using a credit or debit card.
- Stylish
NFC wristbands are available in a wide range of styles, meaning that you can choose one that suits your personality. They are also available in a variety of colors and can be customized with your name or logo.
You can also buy NFC wristbands that double up as fitness trackers. This means that you can wear them all day and use them to track your activity levels.
- Affordable
NFC wristbands are very affordable, especially when compared to other NFC tags, such as key fobs. They are also much cheaper than other wearable devices, such as smart watches.
Even better, their affordability means that you can buy them in bulk and use them for marketing purposes. For example, you could use NFC wristbands as tickets to an event or as part of a loyalty program.
- Guaranteed Efficiency and Security
NFC wristbands offer a high level of security and are very efficient. They use AES-256 encryption, which is the same encryption used by banks. This means that your data will be safe and secure.
NFC wristbands also have a unique ID number, which helps to prevent cloning. This means that you can be sure that each wristband is authentic and has not been tampered with.
