An NFC tag is a small, passive device that stores data and communicates wirelessly with NFC-enabled devices like smartphones. Common specifications include chip type (e.g., NXP NTAG213/215/216), memory (144–888 bytes), operating frequency (13.56 MHz), read range (1–10 cm), and form factor (sticker, card, key fob). NFC tags are waterproof or flexible depending on material. They solve real-world problems by enabling contactless access control, product authentication, smart marketing, inventory tracking, and digital information sharing. By embedding NFC tags into products, passes, or promotional items, businesses can improve efficiency, reduce fraud, and enhance customer engagement.
Description
For example, you can use a tag to store information on various topics at a kiosk. Each tag has specific functionality that lets you use the tag for particular tasks.
In addition to the signaling technologies used by near field communication technology,including NFC TAG Type 1, type 2 nfc tag,NFC TAG Type 3,NFC TAG Type 4 exist. Tag types refer to the speed and compatibility between an NFC tag and NFC readers, and the roles define how active and passive devices respond during a NFC communication. Most often a URL will be embedded in a NFC tag.
URLs take up only a small amount of memory, lowering the production cost of the NFC tags since many are placed on posters or other items that are thrown away later on. NFC tags can, however, hold nearly any type of information, though more memory costs more money.

- Access control

How NFC Tags Work (Working Principle)
The working mechanism of NFC tags is based on electromagnetic induction.
Step 1: NFC Reader Generates an RF Field
When a smartphone or NFC reader is activated, it emits a 13.56 MHz radio frequency electromagnetic field.
Step 2: Energy Harvesting
The antenna inside the NFC tag captures energy from this electromagnetic field.
This energy powers the chip instantly without any battery.
Step 3: Data Exchange
Once powered, the NFC chip communicates with the reader using a standardized protocol such as:
- ISO/IEC 14443 (Type A & B)
- NFC Forum Type 2 / Type 4 standards
Data is transferred in milliseconds, allowing instant interaction.
Step 4: Secure Interaction (Optional)
Advanced NFC tags support security features such as:
- Password protection
- AES encryption (in high-end chips like DESFire)
- Dynamic authentication
- Anti-cloning mechanisms
This enables secure applications like payment, identity verification, and product authentication.
