This is ok, if you have a choice and looking from an individual
perspective. What criteria would an organisation use to determine that
their needs outweigh the need for privacy. (eg. tracking of a person in
a closed area - eg. Mining companies) given that you cannot give people
a choice to adopt a system? Either it is in or not.

What if the purpose is to collect personal data and profile customers?

Unlike barcodes, EPC RFID tags proposed for products, is a serialised
barcode. So a shop would be able to determine that it sold that specific
product and on what date. No need to know who it was sold to.

It depends on the class of RFID chip used. Some chips are WORM. Write
Once, Read Many and some a r/w and some a ROM and fixed at the factory.
I would assume most consumer products would be WORM based.
If verifying that a tag was disable was an issue, then there are simple
ways of verifying this.
Retails could show the EPC RFID number on a customer display and once
disabled, the number would be deleted of the list.

They are referring to deleting the data on the tag (disabling it). Thus
ensuring that the tag is used for its purpose and cannot be used for
The purpose of the RFID is to collect data, so it seams a bit odd that
anyone would delete it.
