credit card (noun)\n\nA plastic card having a magnetic strip, issued by a bank or business authorizing the holder to buy goods or services on credit. Also called charge card.\n\nA credit card system is a type of retail transaction settlement and credit system, named after the small plastic card issued to users of the system. A credit card is different from a debit card in that the credit card issuer lends the consumer money rather than having the money removed from an account. It is also different from a charge card (though this name is sometimes used by the public to describe credit cards) in that charge cards require that the balance be paid in full each month. In contrast, a credit card allows the consumer to 'revolve' their balance, at the cost of having interest charged. Most credit cards are the same shape and size, as specified by the ISO 7810 standard.

I almost always throw it out. I also noticed at the post office where I pick up my mail on days when there is bulk mail the 3 garbage bins are filled to the top with it. I wonder who responds to this stuff? Some people must or they would stop sending it out. Junk mail that comes to me via e-mail I delete without even opening it.

Ninhydrin, (Triketohydrindane hydrate) is a chemical used to detect ammonia or primary amines. When reacting with these free amines, a deep blue or purple color is evolved. Ninhydrin is most commonly used to detect fingerprints, as amines left over from peptides and proteins (terminal amines or lysine residues) sloughed off in fingerprints react with ninhydrin.
