Here is a paper that MG Michael and I wrote back in 2010 for IEEE ISTAS10 - the IEEE International Symposium on Technology and Society.
In 2009, I happened to be in Barcelona, Spain for an "invitation only" Women in Engineering conference organised by the Georgia Institute of Technology. The day before I left Barcelona for the European Conference on Information Systems held in Italy, I was able to speak with the former IT Manager of the Baja Beach Club in Barcelona and conduct an interview with him.
The club in Barcelona began a microchipping experiment which went for 5 years between 2004-2008. The club no longer has this RFID implant patron program. The full interview with the IT manager who implemented the epayment and access control RFID implant system will be released in our forthcoming volume on Uberveillance.
According to the former IT Manager of the club, the whole idea behind of the implant is for patrons was convenience. If the implant acted as an access control mechanism and epayment mechanism, patrons could wear their swimming costumes and utilise both the club services and engage on activities on the beach without the need to carry a purse or wallet and risk being a victim of a theft.
MG Michael and I conducted a significant content analysis using Leximancer and a range of documentation to conduct the analysis in the paper using Roger's Diffusion of Innovation framework.
