What is the difference between an NFC tag and an NFC card?

NFC tag and an NFC card

NFC tag and NFC card are used interchangeably, but there is a significant difference. This blog will teach you the difference between NFC tags and NFC business cards.

These all relate to the same underlying chip technology contained in items of various shapes. For example, a little sticker that can be applied to any object qualifies as an NFC tag, whereas an NFC card is often a credit card.

Another crucial part of an NFC Tag is the NFC antenna. The copper or aluminum object resembling a wire coil wrapping around the chip is the antenna. Using radio frequencies, the antenna communicates with your smartphone or an NFC reader to transfer encoded data. For instance, when you pay with NFC on your smartphone, the antenna sends the payment details from your mobile to the merchant’s payment terminal.

Let us learn the difference between an NFC tag and an NFC card.

NFC tags and cards are typically used to refer to the same thing. These all relate to the same underlying chip technology included in items of various shapes. On the other hand, an NFC card is often something that has the form of a credit card. An NFC tag, on the other hand, can have any feature set (e.g., a little label that you adhere to any object).

NFC tag/card often refers to NFC Forum tags. These basic memory tags hold (freely readable) NDEF data, while some may have the additional processing power. Technologies for NFC Forum tags were initially constructed on top of those for RFID memory tags, which were later all combined into NFC.

Unfortunately, the phrase “NFC card” (as used in the Android literature) is a little confusing when referring to host card emulation (HCE). In the context of HCE, the title “card” really refers to a contactless smartcard (the addition of “NFC” to it is deceptive). NFC devices often accept ISO/IEC 14443-4 in reader mode (i.e., they can handle such smartcards) and frequently also in card emulation mode; a better term would be “NFC-compatible smartcard.”

The NFC Chip

Looking carefully at the NFC inlays, you can see a tiny black dot representing an NFC chip or integrated circuit (IC). The NFC chip looks like a square or dot from a distance, but it becomes much more complicated up close. The NFC chip saves the data you encode on a tiny USB flash drive or SD card. The information may include your name, address, the web address of a website, or your laptop’s password.


An NFC inlay, a primary NFC tag that may be readily transformed into various items, is created when the NFC chip and NFC antenna are combined into a finished version. The most fundamental NFC tag is an inlay; by glancing at an inlay, you can see the chip and antenna. While both items have an adhesive backing, inlays, and NFC stickers are sometimes mistaken for one another. Inlays often come in tiny, low-cost packages and cannot be as fully personalized as stickers. NFC stickers have a paper face element, which enables a more extensive range of forms, sizes, and customization possibilities for the sticky NFC tags. A sticker may be 35 mm x 35 mm, but the NFC inlay can only reach so far.
