The growing use of plastic for payments in America -- at not only McDonald's (NYSE:MCD) and Wendy's (NYSE:WEN) but also gas stations and churches and elsewhere -- has not gone unnoticed in Fooldom. Check out these articles, for example:

A recent Wall Street Journal article noted another milestone passed in the march of charge cards toward total world domination: "For the first time, Americans used cards -- credit, debit and others -- to buy retail goods and services more often than they used cash or check in 2003." Now that plastic appears to be vanquishing cash, what's next? Checks, it seems.

Research from our friends at the Federal Reserve confirms the matter, revealing that "The number of electronic payments, including credit cards and debit cards, last year topped 44 billion, more than the number of checks paid, nearly 37 billion."

Why is this happening? There are several reasons, such as:

  • Convenience. Why drag around a checkbook, which is a lot bulkier than a credit card? Why write out the payee's name, along with the date, payment amount, and more, when a simple signature will do for a credit payment (and sometimes even that's not needed)? Why not take advantage of a brief "float" period, between the time you charge something and when the credit card bill arrives?

  • Perks. Open a checking account and you might receive a toaster or set of gardening tools, but that's pretty much it. Use certain credit cards, and you can enjoy a host of perks, such as air miles and cash back. Many charge cards also offer additional consumer protections.

Using credit cards isn't just a walk in the park, though. There's a dark side to them: Let your purchases get out of control and you'll end up in a death spiral of debt. Major credit card issuers such as MBNA (NYSE:KRB), J. P. Morgan Chase (NYSE:JPM), Bank One, American Express (NYSE:AXP), Capital One Financial (NYSE:COF), and Citigroup (NYSE:C) are making money with the help of millions of households mired in debt. If yours is one of those households, don't despair -- you can get out of debt. Really.
