Near Field Communication (NFC) made it much easier for our gadgets to interact with each other in ”just one tap”. Through NFCs, our phones and other devices can access data from NFC tags.
There are three common NFC tags ICs developed by NXP® Semiconductors to be used in mass market production — Ntag213, Ntag 215, and Ntag216. Though these tags are almost launched simultaneously, they vary in features, specifications, capabilities and potential applications.
This article will compare and contrast these three, giving you a better overview and understanding of how they work.
Understanding NFC Technology and NFC Tags
What is NFC technology?
NFC technology can facilitate short-range wireless communication between devices. It operates using electromagnetic induction and radio frequency identification (RFID) technology.
What are NFC tags?
NFC tags are small devices that store information like contact information, product details, and website URLs. These tags are widely used in marketing, healthcare, manufacturing, and logistics.
The data they hold can then be communicated to other NFC-enabled devices. Nowadays, more and more users prefer to use NFC tags over Bluetooth or Wi-Fi due to their efficient power use, faster connection establishment, and ease of set-up.
Usually, it is a sticker with an antenna, a tiny chip, and a memory. There are a lot of NFC tag variations. However, we will now focus on Ntag213, Ntag125, and Ntag216.
Key Features
Ntag213, Ntag215, and Ntag216 are three commonly used NFC tags, each offering different capabilities and features. Let’s explore their key characteristics:
| Ntag213 | Ntag215 | Ntag216 | |
| User Memory | 144 Bytes | 504 Bytes | 888 Bytes |
| Max URL | 136 Characters | 488 Characters | 872 Characters |
| Total Memory | 180 Bytes | 540 Bytes | 924 Bytes |
| Availability | High | Medium | Low |
| Phone Compatibility | Apple/Android | Apple/Android | Apple/Android |
| Cost | Cheap | Medium | Expensive |
Ntag213
Ntag213 is the new version of Ntag203, as the latter is currently out of production. Its 144 bytes memory capacity allows Ntag13 to store moderate data. This tag variation also has fast read and write speeds that enable quick data transfer between devices.
Regarding security features, Ntag213 only offers basic security features like password protection and data encryption. Despite this tag being the cheapest among Ntag series chips, its versatile compatibility and valuable features are still a win.
Ntag215
Compared to Ntag213, Ntag215 has a bigger memory capacity of 504 bytes. It also provides fast read and write speeds, especially for data transfers.
Regarding its security features, this tag can give you cryptographic authentication making it more enhanced than Ntag213 in this aspect. Ntag215 can also assure you of seamless communications across different platforms.
Ntag216
Ntag216 boasts the highest memory capacity among the three, with 888 bytes available for data storage. This tag offers you fast read and write speeds comparable to Ntag213 and Ntag215. It also provides advanced security features, including a more robust encryption algorithm.
Thus, ensuring data integrity and confidentiality to its users. Like the other two tags, Ntag216 is compatible with a wide array of NFC-enabled devices, ensuring broad applicability.

- It has a flexible memory organization
- Excellent chip for business cards
Cons
- They may have a slightly higher cost due to their larger storage capacity
- It has a limited number of read/write cycles before its performance begins to degrade
- Can be susceptible to various security vulnerabilities
Applications
Why use NFC Tags?
Most phones today already have a built-in NFC inside. So, it means they can receive and transmit data used for payments. You can also use NFC to connect with some peripherals like headphones.
NFC tags can also acknowledge commands like switching on electronic lights, turning on the music, and changing your phone settings. Here are some of the specific uses of each variation:
Ntag213 Typical Use Cases
- PLCR
- Product Information
- Vouchers
- Marketing
- Object Identification
- Bluetooth Pairing
- GS1 EPC/RFID
Ntag215 Typical Use Cases
- Vouchers
- Long Tracking URLs
- Object Identification
- Storing gaming character information
- Collectible items like trading card
Ntag216 Typical Use Cases
- Data storage
- Object identification
- vCards
Choosing the Right NFC Tag: Factors to Consider
To choose the most suitable NFC tag for your application, several factors should be considered:
Tag Positioning
It would be best to consider whether the tag will be embedded within an object or placed on the surface. Its position can impact the reading distance and overall performance.
Size and Reading Distance
Next, evaluate the size of the NFC tag and the reading distance required for your application. Smaller tags are preferable for compact objects, while larger tags provide longer reading distances.
Hostile Environments
Assess whether the NFC tags will be exposed to extreme temperatures, moisture, or physical stress. Some titles are designed to withstand harsh conditions better than others.
Support
Determine the level of technical support and documentation provided by the NFC tag manufacturer, as it can significantly assist in implementing the technology effectively.
Tag Application
Understand your application’s specific requirements and objectives to identify which NFC tag best aligns with those needs. Consider factors such as data storage capacity, data transfer speed, compatibility, and cost.
By carefully considering these factors, you can make an informed decision when selecting an NFC tag that suits your requirements.
