The combination leads to paperless, all digital hospital.....
But while it's a wireless technology, it has never really been mobile outside of a very few, limited environments. Its main limitation has been its requirement for specialized, single-purpose readers. As a result, while general-purpose Wi-Fi networks have become increasingly common, RFID has been limited for the most part to one-off applications. This is now changing with the latest advance in commercially available RFID technology: powered, attachable tags that can be read directly by commercial Wi-Fi APs. This approach, pioneered by Aeroscout Inc., changes RFID from a special-purpose infrastructure to another application on the Wi-Fi network, focusing the cost side of the implementation decision on the cost of tags alone.
