RFID ticket

This RFID provider has marketed quite an interesting RFID ticket: http://rfid.bemrosebooth.com/benefits_of_rfid_tickets.php. But, as I have browsed through the details, I'm afraid there are some privacy issues to be addressed. I do hope that the Chief Security Officer/ Chief Information Officer or the Legal Counsel has conducted some privacy impact assessment on this product. No doubt, it's interesting to be introduced to potential markets like theme parks, bus station operators, tour operators, car parking operators and those who need to use the tickets. I am yet to research the level of success and achieveability by the usage of RFID ticket. Hope something will pop out within few months time.
