The Gen 2 standard that was ratified by EPCglobal in December 2004 is the basis of the Gen 2 tags that are now being shipped by vendors. Improved interoperability and reduced interference are two of the major benefits of the Gen 2 standard. The Gen 2 tags will consume less power and will have kill support. This makes them an attractive proposition for retailers who can look to reduce power consumption costs and allay privacy related fears.
As active RFID tags become smaller and less expensive, their long radio range and ability to work without portals or gates will make them ideal for use with small and low-value objects. As most companies deploy the 802.11 network, active tags can be integrated easily into a companies' existing infrastructure.
