[LETTERS TO THE EDITOR]Privacy lack deters use of credit cards

Whenever I go to a department store, I have a bad feeling about the employees working there. They usually ask me loudly for the secret number of my credit card. If I say the number in a low voice, they ask me once again, "What did you say?" Perhaps it is because their working environment is noisy.

But they do not seem to understand that privacy is key in building a society that is trustworthy.

Even in a crowded and open place, one has to be careful to keep one's private information secret.

When one of my friends went abroad, he experienced a very interesting incident. After enjoying dinner at a restaurant, he paid by credit card. The waiter brought the card along with a card recorder which connects the card with the bank account and asked him to enter the password himself.

In Korea, by contrast, you can find ATM receipts littering the area around the machines.
