    Working up a credit score for Walter Cavanagh has got to be a mathematical nightmare ﹣ the man has nearly 1，500 valid credit cards to his name and holds the Guinness Record for the most credit cards． Mr． Plastic Fantastic ﹣ a title given to him by Guinness World Records ﹣ is also the proud owner of the world's longest wallet， which can hold about 800 cards． But he uses it only to carry a few cards， while the rest are safely kept in bank safedeposit boxes．

Cavanagh started collecting credit cards in the late 1960s． "One of my best friends and I made a silly bet： the guy who could collect the most credit cards by the end of the year would win dinner，" he said． " I got 143 cards by the end of the year， and my friend gathered 138．" After winning that bet， Cavanagh decided to simply keep going with his unusual collection． He got credit cards from gas stations， airlines， bars， and even ice cream stores．

If there's one card missing from Cavanagh's collection， it's that from the Newberry Company． They repulsed his application for a card in the early 1970s， even though he'd collected over 100 by then． They said he had too much credit． Therefore， so far he hasn't had a Newberry card in his collection．

Cavanagh hasn't stopped applying for new cards ﹣ he's held the Guinness Record since 1971 and has no intention of letting go of it． He copies whole pages from a U．S． directory of businesses and keeps sending applications． If he receives a rejection， he writes back to the company explaining his goal and ambition． But he doesn't count useless cards in his total collection．

Thanks to all the cards to his name， Cavanagh has access to about ＄1.7 million at any moment． Despite this privilege， he has managed to maintain an excellent credit score．

The 72﹣year﹣old retired financial planner and credit expert has only one piece of advice to share： "Never use a card to buy anything you can't pay off in a couple of months． If you don't have the discipline， you shouldn't have the cards．"
