Medical research authority of the US have found new cancer in human being caused by silver nitro oxide..
Whenever you buy recharge cards don’t scratch with nails as it contains silver nitro oxide coating and can cause skin cancer...Share this msg with your loved ones ... --------------------------------------------------------------------------------------------------------------------------------
When I tried to know about information about silver nitro oxide, I found the following blogpost on the same subject, as per which the above information is totally wrong.

Search from internet on the same topic (hazards of sliver coat on recharge cards in google search engine) took me to the following post, which is a health study on scratch cards in Nigeria that concludes heavy metal contamination of food after scratching the cards.

Anyway, leaving the information out, we can use some coin to remove the coat on the recharge cards or scratch cards, etc instead of using our nails. The coat is some chemical compound and is better to avoid contact with any chemiclas whenever / wherever it is possible.
If we have to recharge our mobile, we can do the same with credit cards or at the street shop by going physically or if we developed some rapport with him, he can do based on our phone call.
