Have you ever wondered why ETC can automatically deduct fees without stopping? Why can a warehouse manager know what\u2019s on the shelves just by waving a device? This is all thanks to a magical little thing \u2013 the RFID electronic tag. Today, we\u2019ll use the simplest way to uncover its working principle!<\/p>\n

1.What does an RFID tag look like?<\/span><\/span><\/strong><\/span><\/p>\n

An RFID tag looks like a small sticker (or like a laundry label in clothes), but it actually contains two key components inside:<\/p>\n

\u2460Microchip:<\/strong> used to store data (such as product numbers, production dates)<\/p>\n

\u2461Antenna:<\/strong> used to receive and transmit signals<\/p>\n

\"etc<\/p>\n

2.How does it work?<\/span><\/span><\/strong><\/span><\/p>\n

Step 1: The reader \u201ccalls out\u201d\u00a0\u00a0<\/span><\/span><\/strong><\/p>\n

Imagine that the RFID reader is a \u201cloudspeaker\u201d that continuously emits radio waves (similar to Wi-Fi signals). When a tag enters this signal range, it will be \u201cawakened\u201d.<\/p>\n

Active tags:<\/strong> They come with their own batteries and actively send signals like mobile phones (the signals can travel a long distance, up to 100 meters).<\/p>\n

Passive tags:<\/strong>\u00a0They have no battery and are powered by the radio waves of the reader (similar to a solar calculator).<\/p>\n

\u00a0Step 2: Label \u201cReply\u201d<\/span><\/span><\/strong><\/p>\n

The activated tag will use an antenna to \u201csend back\u201d the data in the chip. For example:<\/p>\n

If it is a product label, reply: \u201cI\u2019m product A, produced in 2023\u201d<\/p>\n

If it is an ETC tag, reply: \u201cI am the license plate A12345\u201d<\/p>\n

Step 3: The reader \u201cunderstands\u201d and takes action<\/span><\/span><\/strong><\/p>\n

After the reader receives the reply:<\/p>\n

Supermarket: Add the item to the shopping list<\/p>\n

ETC: Deduct fees from the bound bank card<\/p>\n

Warehouse: Update inventory quantity<\/p>\n

4.Applications of RFID in Daily Life<\/span><\/span><\/strong><\/p>\n

\u00a0\u2460.ETC Charging: The fee will be automatically deducted when the vehicle passes.<\/span><\/span><\/p>\n

\u00a0\u2461.Supermarket Anti-theft: An un-demagnetized label will trigger an alarm.<\/span><\/span><\/p>\n

\u00a0\u2462.Pet microchip: Scan it when the pet gets lost and you\u2019ll know who the owner is.<\/span><\/span><\/p>\n

\u00a0\u2463.Express Logistics: Second-level inventory of full containers of goods.<\/span><\/span><\/p>\n

5.In summary<\/span><\/span><\/strong><\/p>\n

\n
\n

1.<\/strong>RFID tags are smaller than grains of rice and can be implanted into trees to prevent deforestation.<\/p>\n<\/section>\n<\/section>\n

\n
\n

2.<\/strong>In the future, supermarkets can use RFID to achieve \u201cgrab-and-go\u201d automatic checkout.<\/p>\n<\/section>\n<\/section>\n

\n
\n

3.<\/strong>The RFID electronic tag is like a \u201csmall speaker\u201d installed on an item, enabling them to \u201ctalk\u201d from a distance. Although it is a bit more expensive than a barcode, its convenience is changing our lives. The next time you see an ETC or a supermarket anti-theft door, you\u2019ll know what kind of cutting-edge technology is hidden inside!<\/p>\n<\/section>\n<\/section>\n
