I thought I would let ya'll know about a possible threat to your mail. Recently, I recieved a letter from a well-known insurance company. The envelope had a hard plastic card, like a credit card, with raised letters and numbers on it. This was a piece of junk mail, as I did not have a policy with the company. The interesting thing was that their was a carbon imprint on top of the envelope. It seems that someone had run the envelope through one of those old style credit card copiers (you know, where you use carbon paper to make a copy of the card on a piece of paper). This left partial numbers from the machine itself on the envelope. They did not get any info, of course, but it worries me that someone is doing this. Their only mistake was putting the letter back in circulation instead of throwing it away. We have contacted the Postal Inspectors about this. I do not know if this is a new thing or if it has been going on a long time. I just know that I have never heard of it before know. I would like to know if any of ya'll have seen this before or heard of it. So much attention is being paid to electronic security these days, but little is mentioned about postal security.
