What is UHF RFID?
UHF RFID is an abbreviation. UHF is an abbreviation for ultrahigh frequency, while RFID means identifying radio frequencies. In some cases, this technology replaces barcodes as a method of warehouse and supply chain management. RFID marks are located on each object and read the stored data. The UHF RFID brand allows you to manage and monitor inventory without hand scanning. Mobile phones, pagers and satellite communications use this band because it can be divided into a number of partial strips. The distance that the brand is able to transmit depends on the UHF sub-part, while lower frequencies have shorter ranges. The UHF RFID brand can use sub-bands that provide a small 6-foot range (1.8 meters). The transponder or mark contains data and is connected to the item. Antenna Transmits UHF Radio Signal to Transpond, Power and Activation. The activated transponder then transmits data stored on the brand back to the transceiver. Data, such as who has an item whereis an item during transport and placement of an item in a warehouse can be read from RFID.
UHF RFID has a number of advantages over a more common barcode. The mark can have much more data and, unlike the barcode, the data can be added, updated or changed. While it is necessary to navigate the bar -coded item to prevent the barcode to point outwards, the RFID brand may not be visible. Printed barcodes are also prone to carrying or weathering during shipping. The RFID UHF brand can be located inside the protection packaging.
There are two types of UHF RFID brands, active and passive. The active RFID has a battery, allowing them to drive and store large amounts. Governments use these active brands to audit shipments because they cannot be deleted. Passive RFIDs are the most widespread and typical brand can store between 8 kilobytes (KB) and 32 KB of data. Passive marks can be deleted, allowing data to be rewritten andre -use of the brand.
One disadvantage is that UHF RFID brands rely on radio waves and some material can cause radio interference. Factory with steel frames, metal products or liquids can be a challenge for RFID. Bar codes can be more reliable for management of these types of products in the supply chain.
Security and privacy can also be a problem with the UHF RFID brand. In general, brand information is not encrypted and radio waves are easily accepted. Hacker can be able to collect information from the brands simply by standing near the loading dock. Private information, such as customer name or special price, can be picked up and used.
