MasterCard, Visa and American Express are promoting contactless versions of their credit cards, which only need to be held near a special reader at the checkout counter for a sale to go through, making the standard card swiper no longer necessary.
Filters in a new and used cigarette. Cigarette filters are an essential non-tobacco part of a filter cigarette, and have a profound effect on the yield and composition of cigarette smoke. The filter may be made from cellulose acetate fibre, paper or activated charcoal.
All cigarettes are harmful irrespective of their brands. But the toxicity can be reduced by using external cigarette filters. Some of them are Tarlock, Nicofree and Ppuf. But from my experience I have found out that PPuf is more effective than the others.
