RFID means Radio Frequency Identification. RFID technology is simply tags or labels encoded with digital data on store product. This data on the label can be encrypted, storage data capacity is larger, storage information changes freely, and its application will bring revolutionary changes to retail, logistics and other industries. With RFID in retail stores, distribution centers, and the supply chain, retailers can know the location of every item at all times with 99% accuracy. For better tracking, consumer data collection, more accurate inventory, lots of global retailers have implemented RFID in their stores, including the world's most prominent retailers such as Walmart, Target, Kohl's, Nike, and Zebra.They are beginning to harness and unleash the power of RFID throughout their supply chain. The Retail Giant Walmart  has a close relationship with RFID technology. It first adopted RFID technology in 2003 when most of people didn't  knew what this technology was.The experiment proved successful. Walmart saw cost savings and a more efficient supply chain be built through using RFID tags on selecting items. Based on these results, Walmart invest almost $500 million in RFID transformation of shopping malls and warehouses in 2004. Walmart required its top 100 suppliers to adopt RFID technology as early as 2005.  A quantitative relationship experiment on Walmart conducted by The University of Berkeley found that by using RFID, shortages were reduced by 16%, which represented a 16% increase in sales. The replenishment rate of goods with RFID is 3 times faster than without it. Manufacturers of Walmart can choose their own RFID packaging suppliers, but their RFID labels must compliance with the below certification standards as: GS1 RFID serialized encoding standard, Auburn University RFID Lab tag placement standards, ARC inlay standards. ARC Certification aims to ensures RFID tags meet the retailer’s performance requirements. ARC Certification is the best way to evaluate RFID inlay performance.  Just make sure  the test scenario covers all aspects of the use case, there are no shortcuts. XGSun is one of the earliest RFID enterprises in China. We has a strong capabilities of composite, encode, and printing.  We cooperate with Avery Dennison smartrac, the world's best enterprise, to provide all Walmart suppliers with ARC certification RFID labels & hangtags. At the same time, we have the world's leading RFID printer & UV printer, which can provide Walmart project data initialization services for our customers around the world. At present, chips are very shortage all around the world and XGSun's RFID inlays with ARC Certification is also precious. If you need it, please contact with us ASAP.
