RFID, or Radio-Frequency Identification, is a technology that we may not notice daily but is present all around us. RFID tags are embedded in credit cards, pets, and even people. There are billions of RFID tags in use worldwide, making our world more connected.

RFID technology is rapidly evolving and becoming part of various applications. Here's a closer look at its uses and significance.

What is RFID?

RFID tags are tiny devices containing:

1. Computer memory to store an ID and other data.

2. A transceiver to send and receive data.

Passive RFID tags do not have their own power source. Instead, they are powered by radio waves from an RFID reader. When a reader is nearby, it can access data from the tag to identify the item it's embedded in.

Making Products Unique

The most common use of RFID is to uniquely identify products. Here are some interesting examples:

• Fender Guitars: The renowned guitar manufacturer has embedded RFID chips in over 30,000 instruments. These chips help police, dealers, and repair shops identify stolen guitars and return them to their rightful owners.

• Casino Chips: Poker chips embedded with RFID tags allow casinos to track how much money is spent at each table and prevent theft.

• Counterfeit Prevention: Luxury brands like Louis Vuitton use RFID to ensure authenticity. Customers can scan the embedded tag in-store to verify the product's legitimacy.

• Product Tracking: RFID helps factories monitor production times and track equipment like vehicles and machinery across locations.

Useful Facts About RFID

1. RFID can identify over 1,000 tags per second.

2. It’s used in high-tech industries, retail, healthcare, and more.

3. RFID works with liquids and metals.

4. RFID readers can both read and write data to tags.

5. UHF Gen2 tags are cost-effective and growing rapidly in adoption.
