Login hardware that syncs to web

I realise this is perhaps pushing the boundaries of what stackoverflow was designed for, however I'm开发者_运维问答 sure someone knows something about this.

Basically I'm looking for a piece of hardware, card swiper or physical key, that can be programmed to log someone into a website or load a specific program with a set of variables determined by the key. Basically it needs to hook up to a MYSQL database at some point.

If anyone knows anything at all about how to accomplish this I would be very greatful. My programming knowledge is fairly limited so it needs to be relatively plug and play.
