This is old news - the RFID chips was removed from all but the opening and closing ceremony tickets over a year ago; well before the first round of tickets even went on sale here in china. There haven't been any real checks in place to ensure there is any quality to the data that they are given so you could give them anyones photo.
And to the previous comment: one billion rfid tags is nothing; places like hong kong airport would go through that in less than a year. The tagging of animals only applies to those destined for the olympic village, and nobody believes that it is actually being done as the farms don't have the technology.
Places like Shenzhen (Special Economic Zone just over the border from Hong Kong that was a small fishing village) are the exception not the rule - until a couple of months ago the Beijing subway relied on paper tickets being ripped to get in.
China doesnt have the infrastructure or the experience to handle it on such a large scale. The cost is nothing here, and while they may be producing more than anyone else, they produce them for outside china.
