RFID reader are the active core of every RFID system. Their primary function is to communicate wirelessly with RFID transponders (tags) using radio frequency signals in order to identify, read, and—if required—write data. An RFID reader generates an electromagnetic field via its antenna. When an RFID tag enters this field, it is energized either inductively (LF/HF) or via electromagnetic waves (UHF). The tag then responds by modulating and reflecting part of the signal back to the reader, a process known as backscatter.
The device decodes this response and forwards the captured data—such as a unique ID, EPC number, or user memory—to backend systems like ERP, WMS, or MES platforms. Modern devices support anti-collision algorithms, enabling the reliable reading of hundreds of tags simultaneously without line-of-sight, even in dynamic environments.
At IDCRAFT, RFID reader are selected and configured based on real-world application requirements, including frequency range (LF, HF/NFC, UHF/RAIN RFID), read distance, environmental conditions, and system integration. Whether for intralogistics, production, asset tracking, or Digital Product Passport use cases, IDCRAFT supports customers with the right RFID reader hardware for reliable, scalable RFID solutions.
