Types of NDEF Format NFC Tags
NFC tags come in various types based on the NDEF (NFC Data Exchange Format) message formats they support. These types are defined by their storage capacity, data transfer speed, and energy requirements.
- Type 1 tags: These tags are the simplest; they can be programmed and reprogrammed easily. Type 1 tags have a small data storage capacity of about 137 bytes. They have a slow communication speed and a long read/write cycle of about 10 years. These tags are used in simple applications like adding a contact to a phone or linking to a website because they can be easily modified and are inexpensive.
- Type 2 tags: These tags have moderate storage capacity and can be used in slightly more complex applications. Type 2 tags have a data storage capacity of about 1 kilobyte. They have moderate communication speed and a read/write cycle of about 10 years. Type 2 tags are widely used for product labeling, ticketing, and event information sharing.
- Type 3 tags: These tags have a large data storage capacity and are used in high-demand applications. Type 3 tags have a data storage capacity of about 32 kilobytes. They have a high communication speed with a read/write cycle of about 10 years. These tags are popularly used in Japanese service applications, including transport and promotional services.
- Type 4 tags: These tags are flexible and can be used in diverse applications. Type 4 tags have a variable data storage capacity from 1 to 64 kilobytes. They have a high communication speed and a read/write cycle of about 10 years. These tags are widely used for smartphone apps, mobile payments, and access control systems.
- Type 5 tags also use the NDEF format but supports newer features like unique identifiers. They have a variable data storage capacity up to 64 kilobytes. They support higher data transfer speeds and a read/write cycle of about 10 years. These tags can be used for IoT applications, asset tracking, and smart posters to enhance interaction capabilities.
What is NDEF Format NFC Tag Used For
NDEF format NFC tags are used for various purposes and find applications in different areas of life and business.
- Smart posters are one of the primary uses of NDEF format NFC tags. For example, a user can tap an NFC-enabled phone on an NDEF tag embedded in a poster to retrieve information about a product, an event, or a movie trailer. These tags replace QR codes because they are faster and more convenient. They are widely used in advertising, marketing, and information dissemination.
- In business, NDEF NFC tags are used to store and share contact information effortlessly. For instance, business cards come with an NDEF tag, and instead of manually entering the information, a potential client can tap their smartphone to retrieve the information. This use increases efficiency, especially in networking situations.
- An NDEF NFC tag can be used by a manufacturer to track product information throughout the supply chain. For example, a tag can store data regarding current location, inventory, and even shipping. This instantaneous transfer of information can help businesses make quicker decisions and increase operational efficiency.
- Transportation systems use NDEF format NFC tags for ticketing. Commuters can tap an NFC tag on a turnstile, and the tag will retrieve information related the payment which processed instantly allowing commuters to live in a transportation system. This application is faster, secure, and efficient compared to traditional methods.
- In payments, NDEF NFC tags are embedded in mobile wallets and payment cards allowing users to tap and pay without fumbling for cash or cards. This technology makes it easy for secure transactions.
Customization of NDEF Format NFC Tags
NDEF format NFC tags are highly customizable depending on users' needs and the purpose of the tag.
- Data type customization: NDEF tags support various data types that can be customized to send the right message, whether text, a URL, a contact card, or a command for an application. This can be changed, so the message is always appropriate for the user or situation.
- Payload customization: The payload on the tag can also be customized to include more specific information. In a smart poster application, the payload might include a specific URL that leads to promotional content or a specific webpage on a product. This content can be updated without changing the tag physically if the device used to read the tag supports the same configuration.
- Applicability of custom record types: NDEF supports the use of custom record types. Business owners can define specific record types that serve their unique purposes. This is particularly useful in business environments where specialized information exchange is often required. For instance, in the asset tracking example above, a company might create custom record types to hold specific data about the items being tracked.
- Dynamic vs Static customization: NDEF tags can be programmed with static data, where the same information is stored in the tag. This kind of data can also be dynamic, where the information can be updated, for instance, in inventory management or ticketing systems that involve often changing data.
- Access control customization: NDEF tags are also used in access control and security systems. These tags can be customized to hold permissions or access levels for specific individuals in a company. Furthermore, these permissions can be adjusted as needed, ensuring that only the appropriate personnel have access to areas requiring security.
How to Choose NDEF Format NFC Tags
Selecting the right NDEF format NFC tags involves several important considerations to ensure they meet the intended requirements.
- First, buyers must determine the application purpose. Type 1 and Type 2 tags have low capacities and can be used for simple tasks like link sharing or contact info. In contrast, Types 3, 4, and 5 are capable of supporting more complex applications involving bigger data structures like Token generation, product information databases, or mobile payments.
- Next, determine the compatibility with NFC devices. Ensure that the tag can be written and read by the smartphone or other devices intended for use. Different NFC-enabled devices might have varying requirements regarding tag type and data structure.
- Assess the need for rewritability. Some tags, like Type 1 and Type 2, can be rewritten, while others are designed to be written once. Depending on the application, users may want a tag that can be updated with new information.
- Consider the durability and environmental conditions where the tag will be used. Tags to be used outdoors or in harsh conditions should be durable. Some NFC tags are encased in protective materials that shield them from water and extreme temperatures and hard impact so they can last long without getting damaged.
- Evaluate the security features of the tag. In applications involving sensitive data, secure NDEF tags should be considered, which include password protection, encrypted data storage, and unique identifiers to prevent unauthorized access or tampering with the tamper-proof tag.
- Finally, consider the cost and scalability of the tags. Depending on the project or business needs, prices for individual NFC tags or bulk purchase must be assessed. Buyers seeking a long-term solution will account for the future scalability of NFC technology as the business grows.
