An RFID transponder or RFID label is the core element of any RFID system and enables the contactless identification of products, assets, or containers. It typically consists of a microchip and an antenna, integrated into a label, inlay, or robust tag housing. When an RFID reader emits radio frequency energy, the antenna of the transponder captures this energy and uses it to activate the chip. Passive RFID transponders, which are most commonly used in logistics and industrial applications, do not require a battery and are powered entirely by the reader’s electromagnetic field.
Once activated, the transponder responds by transmitting its stored data—such as a unique ID or product-specific information—back to the reader using a process known as backscatter. This communication happens without line of sight and allows multiple RFID labels to be read simultaneously, even in motion. Depending on the RFID frequency (HF, NFC, or UHF), read ranges can vary from a few centimeters to several meters.
IDCRAFT offers a broad portfolio of RFID transponders and labels optimized for diverse materials, environments, and use cases. Combined with the right RFID readers and system expertise, these solutions enable reliable identification, automation, and full transparency across the supply chain.
