Maximizing the Potential of NFC Cards and Tags: A Comprehensive Guide
In the era of seamless digital connectivity, Near Field Communication (NFC) cards and tags have emerged as a cornerstone of convenient and quick data sharing. Let's explore the simplicity and flexibility of using NFC technology.
Encoding/Writing NFC Cards/Tags: The Role of Applications
To begin with, encoding NFC cards or tags is an effortless process, thanks to several user-friendly, free applications available. A notable example is TagWriter. This application stands out for its accessibility and ease of use, offering a cost-free solution to encode your NFC devices efficiently.
Reading NFC Cards/Tags: Is an App Necessary?
When it comes to reading NFC cards or tags, the requirements depend on the device you are using. Most Android smartphones are equipped with NFC functionality, but it's essential to verify this for your specific phone model. You can do this by searching on Google for your phone's NFC capabilities or by checking for an NFC button in the control panel of your phone as in the following photo.
While there is a comprehensive list of phones supporting NFC functionality, it's important to note that new phone models are constantly being released, and they may need to be added to this list. Therefore, always ensure to check the latest information regarding NFC compatibility for your specific device.
The Necessity of Apps for Encoding
While reading NFC tags might not require an app, encoding them is a different story. To encode an NFC card or tag, an application is indeed necessary. This process can be executed at any time, adding to the flexibility of NFC technology.

FAQ:
Q: I Can't Read the Tag/Card – How Do I Know if My Card is Even Encoded?
A: If you're having trouble reading your NFC tag or card, it's essential to determine whether it's been encoded. Here's a simple guide to check the encoding:
-
Open Tagwriter app: Begin by launching the Tagwriter app on your device. Then press on 'Read tages'.
-
Prepare Your Card for Scanning: When you see the prompt 'Ready to Read Content and View Results', gently tap the NFC card against the middle of the backside of your phone for scanning.
-
Check for Encoding Information: If your tag or card has been encoded, the app will display the encoding details. This information confirms that your NFC tag or card is active and contains encoded data.
Q: I am receiving an error message: 'Store Fails. NFC Data Set is Too Large'.
A: The storage capacity of NFC tags/cards varies by type. For instance, NTAG213 cards have a memory of 144 bytes, NTAG215 cards have 504 bytes, and NTAG216 cards offer 888 bytes. It's important to ensure that the information you encode fits within your card's memory capacity. If you're encountering difficulties fitting your information, consider optimizing the data or using a card with a larger capacity.
It's worth mentioning that a few bytes of any NFC tag/card, such as NTAG213, NTAG215, and NTAG216, are allocated for the NFC tag/card itself. This means, for example, an NTAG214 card might have 137 bytes available instead of 144 bytes, as a portion is reserved for system use, like the serial number. It's normal for these bytes to be unavailable for user data.
However, there's no need to worry about the space for your data. These cards/tags work efficiently by storing only a URL link to your profile that contains all the information you wish to share. This URL typically requires only about 20-40 bytes, making even the cards with lesser user-accessible memory perfectly suitable for this purpose.
Q: I've encoded my NFC tag/card within its memory limits, yet it's readable only on Android devices and not on iPhones. Why might this occur?
A: iPhones have specific compatibility criteria for reading NFC tags/cards. Notably, iPhones can only read URLs encoded on NFC devices. If your NFC tag/card is encoded with contact information or other non-URL data, it will not be accessible via iPhone. Android devices, on the other hand, are capable of reading both URLs and contact forms from NFC tags/cards.
To ensure cross-platform compatibility, we recommend encoding your NFC device with a URL that directs to a webpage containing all your relevant information. You can use our NFCtube, the app.nfctagify platform, or other similar software solutions like Linktree, HiHello, etc., to create these URLs.
Q: Do I need to touch the card with the phone, or can it be scanned from a few centimeters away?
A: To scan an NFC card using your phone, you typically need to bring the phone in close proximity to the card. Here's a refined explanation:
Distance for Scanning: NFC cards are passive tags and are activated by the NFC reader in the phone. Usually, you need to touch the card with your phone.The exact distance can vary depending on the phone's make and model, as some NFC readers may be more powerful than others.
Dependence on Phone and Reader Type: The effectiveness of NFC communication depends on the types of both the NFC reader (your phone) and the NFC card. Different phones may have varying NFC reading capabilities.
Antenna Position Variances: The position of the NFC antenna varies between different devices, including between Android and iPhone models. This positioning can affect how you should hold your phone to scan an NFC card.
Previous NFC Interactions: If your phone was recently in proximity to other NFC resources, it might take longer to read a new NFC card. This is because the phone may continuously try to read NFC signals in its vicinity.
Ideal Method for Android: For optimal NFC reading on Android devices, it is typically recommended to tap the NFC card against the center of your phone's backside. This is because the NFC antenna in most Android smartphones is located in this area.
By considering these factors, you can achieve a more efficient and quicker NFC scanning experience with your phone.
