What is RFID?
RFID (Radio Frequency Identification) is a technology that uses radio waves to identify objects through special tags or cards. An RFID system has two main parts:
Tags or Cards: Hold information (namely just a 7 digit UID) and respond to signals.
Readers: Devices that send signals to tags and receive the stored information.
Passive RFID tags come in three frequency types:
Low Frequency (LF) and High Frequency (HF): Short range, just a few centimeters.
Ultra High Frequency (UHF): Longer range, over one meter.
Common uses: inventory tracking, access cards, animal tags, logistics.
What is NFC?
NFC (Near-Field Communication) is similar to RFID but has extra features. NFC devices can both send and receive information, allowing two devices to communicate with each other directly. NFC works at close range (a few centimeters), making it ideal for secure transactions like payments and access control.
Common uses: contactless payments, secure entry, mobile pairing, digital business cards
The main difference between the two products is that NFC can transmit not only its unique ID (UID) but also information in the form of text making it great for business cards and URL's or Web Links
Quick Comparison:
Communication:
RFID: Usually one-way (reader to tag) and transmits only a 7 digit UID
NFC: Two-way (both devices can communicate).
Read Range:
RFID: Short to medium range (LF/HF: a few centimeters; UHF: over one meter).
NFC: Very short range (a few centimeters).
Best For:
RFID: Tracking objects or access control at various distances.
NFC: Secure and close-range interactions like payments, secure access and transferring links or business card details
