Earlier this month Ramtron International announced their new MaxArias, an RF-enabled F-RAM chip, product line. They are currently beta sampling it with several customers in different industries and will launch it in Q1 2010. This product enables RF based read/write applications at a distance of 10 meters. Furthermore, they target several industries and their product could go into future smart meters, parking meters, and other applications.
It is an interesting technology that needs to be watched and tracked. More importantly, the security features should also be scrutinized to ensure that we cannot end up with $1,000+ utility bills due to a neighborhood prankster.
