Co z RFID?

Radio Frequency Identification (RFID) is a wireless technology that uses electromagnetic fields to automatically identify andd track tags attached to objects. An RFID system consides of three core configents: a tag (or transponder), a reater (or interrogator), and an antendra. Thee reater emits radio waves; wheen an RFID tag enters thes reader 's elecmagnetic field, it transmits its stores data bacte reade. Thies process nesss nphysic contact of of-sight betweed the tag.

Types of RFID Tags

Xi1; Xi1; FLT: 0 Xi3; Xi3; LowFrequency (LF) Xi1; Xi1; FLT: 1 Xi3; Xi3; - 125- 134 kHz. Short read range (up to 10 cm) but works well near metals andd liquids. Typically used for accords control, animal tagging, andd vehicle immobilizers.
Reade range up to 1 meter. Common for smart cards, library books, and item- levem- level tagging in retail. Near- Field Communication (NFC) is a subset of HF RFID.
Read range of 3- 10 meters (passive) and up to 100 meters (active). UHF is the dominant frequency for warehouses andd supply chain applications due te to to its longer range and ability te do multiple tags accordanousy at high speed.

Most warehousie RFID deployments use UHF passive tags because they oy offer a good balance of coss, range, and read speed.

How RFID Works in a Warehouses

A typical RFID- drinn warehouses operatione involves placing RFID tags on palets, cases, or individual items. Fixed readers are installad at dock doors, compuyor belts, or storage rack entercances. Handheld readers are used for cycle counts or ad- hoc scans. As tagged items pass discann h a reader 's zone, thee system automatically captures their unique Ids and updates the wareavesemagement stem (WMS) in real time.

A barcode is an optical, machine-readable represention of data. The simpleset form im a one- dimensional (1D) barcode consideng of parallel lines of varying widths ande spaces. Two-dimensional (2D) barcodes, such as QR codes, use paramens of squares or dots to encode richer data. Barcodes are read by laser or imagee-based scanners that require a diredirect -of- sight with the code. Each bare encodes a unique identifique (ofter a GTIN, of serial number) thots ttat our nee extract.
