I have this reader and the APC Bio-something. And the APC is sooo much better. I find myself teaching this reader my password 9 times out of 10, and using it only shortly after. Perhaps a software issue. Either way, you shouldn't have to think about it. The APC, I am never worrying about...I know it's there and ready. Too late to return this - but beware.
