................and have cash options for those customers who aren't comfy with recurring automatic transactions on their card or account.
This seems to be a new-speak definition of cash: that they send you a bill instead of making an automatic withdrawal?
We have an anonymous account option.
Great. I wonder how many of their customers take advantage of this option, and how it works. The emitting chip is stated not to contain any information other than 'ID so-and-so passes point X now'. Does one have to keep track of one's credit status and go to an office and pay with paper bills in advance? Not very convenient.
Our records are much like those kept by the phone company -- they're sealed to the public and to official requests that aren't accompanied by a court order.
Ah, the records are GAKed. For convenience, the PD could as well tap into the system in real-time. They have always thousands of stolen vehicles to watch out for.
We don't ever purge our records.
What would be the reason for this? When a customer has paid his bill, the detailed records have no consequences for their profit. For long-term highway traffic analysis they could as well create deidentified entries. Stockholm is to get the first toll system ever in Sweden, in a few years (for crossing into the inner city). From what has come out so far, they are contemplating the use of Chaum's anonymous toll system (alledgedly in place in Dutch cities). How does this system work, cryptographically?
