When Metaphors Fail to Keep Their Distance

Was I being too literal when I made the following change? I don't think so. A name-brand financial columnist wrote the following paragraph in a piece about Web-based credit cards: Most issuers mail you a plastic card, usually a MasterCard or Visa, which you also can use in stores. At Citibank, however, plastic has become uncool. Instead, it's offering ClickCredit, a virtual card (www.clickcredit.com). It acts like a credit card, but exists only in Citi's computer. You use it solely for making purchases on the Web. The problem is, I have one of these Citibank cards, and while it's true that it's not an ordinary credit card that you carry around in your wallet and use at stores, it's also true that the ClickCredit people do mail you a card, and it's made of plastic.
