IMPORTANT NOTICE...about the enclosed 1973 telephone credit card.
To make certain no unauthorized
person is using your card, the telephone operators who handle credit
card calls may ask you a question or
two whenever you place such a call.
They're the type of question that
can be answered easily and quickly
by a person having a credit card, but
should discourage an unauthorized
user from trying to complete the call.
Since credit card owners are receiving these notices with their new credit cards we can expect to play some games with the operators this year. Don't sweat, the questions are only designed to scare you and make you hang up, thus giving it away. Though you might get a few questions like the name of the company, city or area code of the credit card number, you'll have no problem if you keep cool. The operator knows at most the name of the city and area, code, not the company's name. So have your number memorized, and if you need the code numbers for certain cities, get YIPL #8, and be sure to read our reprint on making credit card calls. Also write in and tell us what kind of questions operators are asking in your part of the country.Dear YIPL While living at an Indian Reservation I learned an old Apache phone phreak technique. Simply take a penny and rub it down to the size of a dime. The pavement works well.
Take some plaster of paris and drop a quarter into it.
Let it harden, and then very gently take out the quarter.
You should have a smooth and accurate mold. Now fill with water
and put into the freezer compartment of your refrigerator.
When the water freezes zou have a piece of ice you can use in all
sorts of machines. Sometimes foil or other insulator is used to make it
easy to pull out the ice.
