A couple questions:
Are you presenting?
It sounds like "no". If you were, this would be a bigger deal, as companies may have a serious stake in whether or not you present as a representative of the company - and it can go either way. In some jobs it can even be a big deal to try to present as a private individual if you are presenting in a capacity close to what you do for work. If I'm wrong, and you are presenting, then I'd say talk to your manager and go from there.
It's much, much less of a big deal what your badge says when you pay and attend a conference as a regular attendee. Particularly in a big conference hosted by a conference hosting organization - it's mostly a way of identifying you and helping you find others who are interested or connected to things you are connected to.
Did your company pay or did you?
Since I attend conferences both as a private person (I even run them for fun... perhaps I'm crazy...) and as a part of my job, I'm particularly sensitive to this. My general thought is that if it's on your money, you can (and almost should), skip referencing your association with your company. Most places I work are all or nothing - either they pay for the conference and my time, or none of it - I pay, I take vacation to attend (or go on the weekend), etc.
If your company is paying the bill, check in as a courtesy with your manager to see if there's any strong preference. At times, even when I was just an attendee, tiny companies of mine wanted to make sure that I represented them to show that they were out there in the marketplace. At other times, my company really doesn't care, because they are mostly interested in the information I bring back, not in the reputation of sending me. Either way, my deal is, when they pay, they have the right to choose how I represent myself.
What kind of company?
I've found that different industries are touchy in different ways. Small consulting companies are almost always aggressive in representing themselves. Big companies can be touchy about reputation and image.
