What is a computer "trick" that in the past was cool, but today is unimpressive and trivial?

This isn't a "computer" trick. It's actually a phone trick. 1. Tap a business's phone used to process credit card charges. 2. Record all phone calls made on it for however long the tape is (or nowadays you can have unlimited length with audio files). 3. Each frequency corresponds to a numbered button on the phone used to transmit the credit card numbers and expiration dates. 4. Decode the tones to find out which numbers were transmitted. 5. You now have a list of many credit cards along with their expiration dates that you can steal from. It's the oldest trick in the book and if you claim to have discovered it, hackers will laugh you into oblivion.

Use the frequency listing provided by the old ad and use a small, non-detectable device to pick up the call on the telephone. 9. The bank may have a code that will allow them to pick up the telephone call. 10. Use that code to log into the bank's computer system. 11. Search the bank's internal databases for the names of employees. 12. Use this information to obtain your names. 13. With your names and bank information, purchase your stolen credit cards. 14..
