Abstract
A key is provided with a memory in which, without user intervention, it collects data relating to lock operations each time the key interacts with a lock. This data is subsequently downloaded from the key to a computer. In some embodiments, the keys collect data relating not just to their own transactions, but also poll lock memories for the locks' prior transactions as well. By this arrangement, a patchwork collection of redundant data can be developed in the computer, improving data integrity and reducing data latency.
