In the evolving landscape of technology and sustainability, it's easy for acronyms to become tangled in the public consciousness. Two such terms—NFC and NFT—have recently come under the spotlight, sometimes causing confusion. That's why we're here to clarify our use of NFC technology and distinguish it from NFTs.

Near Field Communication (NFC): A Closer Look

NFC stands for Near Field Communication, a technology that enables wireless communication between devices (e.g., smartphones, tablets, laptops, etc.) within a short range, typically up to 4 cm. It's built upon Radio-Frequency Identification (RFID) technology, emphasizing secure communication in close proximity, which enhances security by minimizing the risk of interception by unauthorized devices.

It's the same technology that powers contactless payments, ticketing systems, and, yes, the personalization features of COVER products. NFC allows our community to embed personal messages, videos, or photos onto their eco-friendly gift wrap, track its journey around the world, and monitor its environmental impact in real-time, making the gift-giving experience unique, memorable, and sustainable.

How NFC Works

NFC enables two-way communication between endpoints. There are two modes of operation in NFC:

Passive Communication Mode

NFC tags in passive mode do not require their own power source, drawing energy from the electromagnetic field produced by the NFC reader device (such as a smartphone) instead. Once powered, the NFC tag can then transmit its stored data back to the reader, completing a cycle of two-way communication. This energy efficiency is particularly beneficial for sustainable product designs, as it minimizes the environmental impact and allows for the creation of lightweight, compact tags. This mode, as mentioned above, is used in applications like contactless smart cards, ticketing systems, and our COVERs.

Active Communication Mode

In active mode, both devices generate their own electromagnetic field to enable two-way communication. This flexibility allows for a wide range of applications and is used for more complex interactions like smartphone payments, device pairing, and data sharing.

Key Features of NFC Technology

Unique Identifier (UID)

Each NFC tag is embedded with a unique identifier that ensures its distinctiveness. This UID is a crucial feature for security and authentication purposes, making NFC tags an excellent choice for applications that require a secure and personalized interaction, such as payment transactions and personalized content delivery.

High Security

NFC incorporates built-in security standards that support encrypted data exchange. The technology's design inherently protects against eavesdropping and data tampering. This makes NFC suitable for sensitive transactions, including financial services and personal data sharing.

Versatility and Ease of Use

NFC is designed to be interoperable across different devices and manufacturers. This universal compatibility ensures that NFC-enabled devices can communicate with a wide range of tags and readers, promoting widespread adoption and ease of integration into existing systems. Users can simply tap or bring their NFC-enabled device close to an NFC tag to initiate communication, making the technology accessible and convenient for everyday use.

Application in COVER products

In the context of COVER's eco-friendly reusable fabric gift wraps, NFC is not just a feature; it's a statement of commitment to innovative, environmentally friendly gift-giving. The tags serve as a bridge between the physical and digital worlds. By embedding a small, passive NFC tag onto each wrap, COVER transforms traditional gift-giving into an interactive, personalized experience. Here’s how:


The integration of NFC allows each COVER wrap to carry a unique digital signature, enabling customers to attach personalized messages and content to their gifts in a secure and environmentally friendly manner. This not only enhances the gift-giving experience but also aligns with COVER's commitment to innovation and sustainability, setting it apart from traditional gift-wrapping solutions.

Recipients can tap their NFC-enabled smartphone against the COVER to access personalized messages, videos, or photos, as well as real-time information about the environmental impact of the fabric gift wrap. This feature adds an emotional depth to the gift, making the experience memorable.

To accommodate all users, including those whose mobile phones may not support NFC technology, COVER has thoughtfully included an alternative method of accessing the unique content. Each NFC tag comes with a COVER ID engraved on it, allowing users to manually enter this ID if needed. This approach ensures that the innovative experience offered by COVER is accessible to everyone, bridging the gap that technology differences might create.


COVER's NFC tags are thin, lightweight, and have a negligible environmental footprint, especially when compared to the waste generated by traditional, single-use wrapping paper. The tags are not only crafted from recycled materials but are also engineered to operate without an external power source, ensuring they remain functional for many years to accompany our reusable fabric gift wraps on their journey around the world, further cementing our commitment to sustainability and reducing environmental impact.


This innovative technology not only prolongs the lifespan and enhances the emotional value of every gift but also promotes reuse, further minimizing waste.

The durable design of COVER wraps, combined with the reprogrammable nature of NFC tags, means that each wrap can be used—and personalized—time and time again, significantly reducing waste for many years to come, greatly surpassing the minimal impact of the tags themselves.

Non-Fungible Tokens (NFTs): An In-Depth Look

NFTs, or Non-Fungible Tokens, are digital assets that represent ownership or proof of authenticity of real-world objects like art, music, in-game items, and videos, primarily using blockchain technology. They are bought and sold online, frequently with cryptocurrency, and they are generally encoded with the same underlying software as many cryptos. The term "non-fungible" means that these tokens are unique and cannot be replaced with something else. For example, one Bitcoin is always equal to another Bitcoin; hence, Bitcoin is fungible. However, one NFT is not equal to another NFT, making each NFT distinct or "non-fungible."

How NFTs Work

NFTs exist on a blockchain, which is a distributed public ledger that records transactions. Currently most NFTs are part of the Ethereum blockchain, although other blockchains support them as well. Each NFT contains unique information that makes it different from other NFTs. It's this information that makes them valuable as digital proof of ownership of the unique item or piece of content.

For an NFT to accurately represent a physical product like a COVER gift wrap in the digital realm, a reliable method of physical-to-digital identification is essential. This identification process ensures that the digital token on the blockchain corresponds to the specific physical item it represents. Currently, COVER employs NFC (Near Field Communication) technology to bridge this gap. Each COVER wrap is equipped with an NFC tag that carries a unique identifier, enabling it to connect the physical product with digital information or actions seamlessly. This system alone effectively supports the tracking of each COVER's journey and its environmental impact without the need for NFT technology. Hence, the inclusion of NFTs would not enhance the functionality or sustainability tracking already achieved through NFC technology.

The Environmental Debate

While NFTs have opened new avenues for digital art and ownership, their current environmental footprint—primarily due to the energy-intensive processes associated with blockchain transactions and mining—has led many eco-conscious consumers and creators to seek alternatives or call for more sustainable blockchain solutions.

Energy Use

Blockchain transactions, including those involving NFTs, require significant computational power, which in turn requires a considerable amount of electricity. The Ethereum network, which hosts the majority of NFTs, currently uses a proof-of-work (PoW) system that is particularly energy-intensive.

Carbon Footprint

The energy required for these transactions often comes from power plants that burn fossil fuels, contributing to carbon emissions. This has led to debates about the carbon footprint of NFTs, particularly in the context of digital art and collectibles.

Moving Towards Sustainability

The blockchain and NFT communities are actively exploring solutions to mitigate environmental impacts. 'Green' blockchains like Cardano are at the forefront of this movement, aiming to make blockchain technology more sustainable. One significant development is the transition from a proof-of-work to a proof-of-stake (PoS) consensus mechanism, which is expected to reduce the network's energy consumption dramatically.

Additionally, some NFT platforms are beginning to invest in renewable energy projects or purchase carbon offsets to lessen the environmental impact of their operations.
