My opinion is not valuable, since I don't know the laws in your jurisdiction. Since, in order to have a proper DNR order in your jurisdiction, you probably need to talk to a doctor, you should just ask them what the requirements are. Again, in New Jersey, what you say will be sufficient, and you can even have a DNR bracelet which is accepted without any further documents, but it's not just some bracelet which says "DNR", it is a non-removable hospital-type bracelet of an official design which has the name of the physician on it, if I recall. What I am trying to discourage is people engraving "DNR" on whatever bracelet or necklace they have, or tattooing it on their chest, without consulting a doctor or getting a proper order or anything else. This will generally not be sufficient, although, again, I don't know for your country or state or town specifically. EDIT: Let me just add that for most people, a living will is really what they want when they think of preventing lingering in the ICU. A living will can say, for example, that in case you become unable to function, and your condition will not improve according to your doctors, you do not wish to be placed on a respirator, or have feeding tubes inserted, or to be resuscitated. (Of course you should consult advisers to put this together.) A living will is not the same as a DNR order; it is more general. I think for most people it doesn't hurt to have it. On the other hand, walking around with a DNR order on you, if you are a person without a known great risk for cardiac arrest, is kind of pointless, IMO. You may, after all, become incapacitated in ways that do not involve cardiac arrest (like traumatic head injury or stroke).
