RFID tags
RFID stands for Radio Frequency Identification. RFID tags are equipped with a microchip and an antenna that allow them to communicate wirelessly with an RFID reader via radio waves. This enables information to be read or transmitted remotely, without physical contact between the tag and the reader. At NFC World, you’ll find RFID tags in a variety of designs, ranging from standard access cards to specialized tags for logistics and inventory management.
How does an RFID tag work?
An RFID tag consists of a small microchip with an antenna. As soon as an RFID reader comes near the tag, the reader sends out a signal that activates the tag. The tag then sends the stored information back to the reader, which decodes these signals and uses them to identify the object, card, or person. RFID tags come in two types: passive tags have no power source of their own and are activated by the reader’s signal, while active tags do have their own battery and can therefore be read from greater distances.
The most commonly used chip for RFID tags is the MIFARE Classic 1K, which operates at 13.56 MHz. This chip offers 1 kilobyte of storage and is widely used in access control, time tracking, and locker systems. For simpler systems that only require a unique serial number, the EM4100 at 125 kHz is a cost-effective alternative. If you have higher security requirements—for example, in government buildings or server rooms—the MIFARE DESFire offers the same functionality as the Classic 1K but with more advanced encryption.
RFID chip types and how each type supports your use case
RFID tags are used for a wide variety of purposes. For access control, you use an RFID tag as a pass to go through gates, open lockers, or take the chairlift on the slopes. RFID tags are also widely used for time tracking in the workplace: employees scan their passes upon arrival and departure, which automatically records their hours.
In addition, RFID tags are widely used in logistics and inventory management. By attaching an RFID tag to products, you can quickly and accurately track the location of items in a warehouse and monitor remaining stock levels without having to scan each item individually. RFID tags are also used in healthcare, for example, to identify and track medical equipment or patient records.
Frequently Asked Questions
What are RFID tags?
RFID tags are small electronic devices that contain and can transmit information via radio waves. These tags consist of an antenna and a microchip that stores the information. They can be attached to objects, animals or even people to help track, identify and manage these items. RFID tags are used in various applications such as access control, logistics, inventory management and even healthcare.
How do RFID tags work?
RFID tags work by means of radio waves. When an RFID reader is placed close to an RFID tag, the reader emits a signal that activates the tag. The tag then sends information back to the reader via radio waves. The reader decodes this information and can use it for various purposes, such as identifying the object to which the tag is attached or checking a product's inventory levels. RFID tags can be passive or active. Passive tags do not have their own power source and are activated by the signal from the reader. Active tags have their own power source and can actively transmit signals, allowing them to be read at greater distances than passive tags.
