Radio Frequency IDentification (RFID) tags can transform costly operational and logistics activities into ‘touchless’ processes, using wireless automation. Early adopters of the technology initially realised efficiency benefits linked to mechanical and/or repetitive processes. Hotels were among the first to recognise these types of applications in areas such as automating access to guestroom locks. But the potential for RFID goes much further than this, particularly once you start to exploit its ability to help gather real-time human activity data.
