How to create an NFC business card with Cardokey that fits the memory size of your NFC media?

The intelligent system of Cardokey

One of the most interesting features of Cardokey is the automatic management of the memory size of forms. The contact form indicates in real time the actual occupancy of the NDEF memory based on the number of characters. The Cardokey user knows the type of vCard information. He can store it according to the memory size. The memory size depends on the NFC media.

The different types of NFC Media and their memory size

It is possible to make a vCard with a minimum of name, surname and email information for a very small NFC memory4. For example, on an NTAG Nano, which has a capacity of 160 bytes and can store NDEF messages of up to 128 bytes, one can store basic information like a person’s name, surname, phone number, and email address.

Or, more complete information can be stored on a ST25TV02K chip, which has a capacity of 256 bytes and can store NDEF messages of up to 224 bytes. In this case, one can include a person’s name, surname, title, organization, phone number, email address, and postal address.

The steps to create an NFC business card with Cardokey

You can create NFC business cards that fit the memory size of your media without losing information. This allows you to optimize the use of your NFC Media and take advantage of their full capabilities.

To create NFC business cards that fit the memory size of your media, simply follow these steps:

  • Open the Cardokey app and choose the type of content you want to create (business card, URL link, social media link).
  • Enter the information you want to share in the contact form. The form tells you in real time how much memory your data is occupying and how much memory is available on your media.
  • Hover your smartphone to the NFC media of your choice. The app writes the data to the NFC media and confirms that the NFC business card has been created successfully.
  • Test your NFC business card by scanning it with your smartphone or another NFC phone. You’ll see the information you’ve shared on the screen.

That’s it, you’ve created an NFC business card adapted to the memory size of your media, thanks to Cardokey’s automatic form memory size management feature

How Cardokey protects your data with EviSwap NFC NDEF technology

The innovative features of EviSwap NFC NDEF technology

Cardokey uses EviSwap NFC NDEF technology by Freemindtronic for cybersecurity. This is an innovative technology that lets you create and share digital contacts contactless for life. With a simple click, you can create NFC business cards on any NFC media, whether it is disposable or not. You can give a new use to NFC tickets, cards, labels, and tags. You can also rewrite your NFC business cards at least a million times without any risk of error. You can use them for more than 40 years without needing a power source.

The standard and secure format of EviSwap NFC NDEF technology

EviSwap NFC NDEF technology is a technology that uses NFC to facilitate data exchange by implementing the NDEF NFC standard. NDEF stands for NFC Data Exchange Format. It is a standardized format that contains structured data, such as contacts, links, texts, images, etc. NDEF files are compatible with most computer and phone terminals, which can read and write them directly on the NFC memory. EviSwap NFC NDEF technology is especially used by Freemindtronic to exchange encrypted data from human to human from an NFC media, ensuring data security and privacy.

The performance and durability of EviSwap NFC NDEF technology for industrial chips

EviSwap NFC NDEF technology is also compatible with all NFC NDEF media, but it has the advantage of being optimized for Freemindtronic’s NFC HSM industrial chips. These chips can operate in a wide range of temperatures, from -40°C to +85°C. They can withstand harsh environments and resist shocks, vibrations, and water. They are ideal for applications that require reliability and robustness, such as logistics, manufacturing, or security. Moreover, EviSwap NFC NDEF technology is optimized to exchange the largest quantity of information stored in a large NFC memory. For example, it is possible to store NDEF messages of up to 7.9 kilobytes on an M24LR64E-R chip, which has a capacity of 8 kilobytes. In this case, one can add all types of vCard data as well as security keys, digital signature keys and other custom data.

Cardokey: the anonymous and reusable solution for creating NFC business cards

Cardokey is a secure and reusable solution. The Cardokey app works anonymously. It is not connected to a remote service. It does not store in the phone the data. It does not ask you for any information about the user. Finally, it works in real time in Air Gap Network Security . The EviSwap technology also includes an intelligent system to optimize the memory management of NFC media. The goal is to improve the user experience. The intelligent system informs the user in real time of the limits imposed by the maximum size of the NDEF memory available in the media. This allows you to easily store data according to the memory size.

Cardokey, an eco-friendly application

Cardokey isn’t just a universal app for people worldwide; it’s also eco-friendly, allowing you to recycle NFC media and reduce their environmental impact.

How Cardokey recycles NFC Media

NFC media, such as tags, cards or bracelets, are made of several elements and materials, such as PET (polyethylene terephthalate), aluminum or copper for the antenna, a silicon NFC chip, gold or other metals, and an adhesive. These materials are not all easily recyclable, and can cause pollution or waste problems. For example, PET is a common plastic, that is used in many consumer products, like water bottles or packaging. Although PET is recyclable, when it is used in large quantities and in the form of an NFC tag, it is hard to separate PET from other components for recycling, and it tends to clog the treatment filters. Moreover, the metal of an NFC antenna is difficult to recover and recycle. Finally, the NFC chip itself contains precious metals, that are often lost during the recycling process.

To avoid these problems, Cardokey offers an innovative and ecological solution: it allows you to recycle NFC media by reusing them to create new NFC business cards. Instead of throwing away your old NFC tags, cards or bracelets, you can transform them into NFC business cards with Cardokey, and give them a new life. You can also use existing NFC media, such as transport tickets, or access badges, and convert them into NFC business cards with Cardokey. You can thus enjoy all the benefits of NFC technology, without generating additional waste.

How Cardokey works with different types of NFC chips

Cardokey recycles all types of NFC chips (1, 2, 3, 4 and 5), regardless of ISO standards (14443, 15693, 18092). It detects chip types and adjusts accordingly for maximum compatibility. For example, Cardokey can read and write to NFC chips that have enough memory to store information, such as NTAG, MIFARE or ICODE chips. However, Cardokey will not be able to format, erase or modify NFC chips that are permanently locked.

How Cardokey helps you create personalized NFC business cards

By using Cardokey, you can recycle NFC media and turn them into personalized NFC business cards, that contain the information you want to share, such as your name, company, title, website, email, phone number, and more. You can also create URL links to documents or presentations that are useful for your business, such as quotes, contracts, portfolios, and more. You can also create pre-configured links to your favorite social networks, such as Deviantart, Discord, Facebook, Flickr, GitHub, ICQ, Instagram, LinkedIn, Mastodon, Medium, Pinterest, Reddit, Skype, Slack, Snapchat, SoundCloud, Spotify, Steam, Telegram, TikTok, Tumblr, Twitch, Twitter, VKontakte, WeChat, WhatsApp, YouTube, etc. Finally, you can manage your data and contacts in the NFC card, edit or delete them at any time, and view them on your phone or card.

How Cardokey contributes to the preservation of the planet

If we consider the 14 languages ​​available in the Cardokey application, this represents more than 3.7 billion potential users. These potential users can each recycle 10 NFC media each year. This represents 37 billion NFC supports annually. This reduces the environmental impact of NFC and helps preserve the planet.

How Cardokey is eco-friendly and compliant

Cardokey is an eco-designed solution that contributes to the UN Goal 12. This goal aims to ensure sustainable consumption and production patterns. It complies with ISO 14001, Basel and WEEE standards. It also follows international standards for eco-responsible practices, circular and solidarity economy, sustainable economy and carbon footprint reduction. In addition, Cardokey complies with various standards and regulations. These include ISO/IEC 7816-4, ISO/IEC 14443, NFC Forum Type 2, ISO/IEC 18092 and ISO/IEC 15693. It also follows international law rules on the protection of private and professional data. These include the General Data Protection Regulation (GDPR), the Personal Information Protection and Electronic Documents Act (PIPEDA), the California Consumer Privacy Act (CCPA), and others.

Cardokey therefore offers you an innovative and ecological solution to create NFC business cards that look like you and that suit your needs. Thanks to its recycling feature, you can also reuse NFC media and turn them into personalized NFC business cards.
