I probably would use the internet more to purchase items, but I am always a bit worried about giving my credit card number out online. I also am a bit concerned about the identity theft that is happening everywhere and if I should even continue using my credit cards.
More and more companies are accepting credit cards on their websites and it is certainly a time saver to shop online and have your purchases delivered to the door.
I have had one occasion where someone bought airline tickets on my card, how they got my number I have no idea. Fortunately I did not have to pay for them as the credit card company did. The other time, we got a call from the police saying someone has been picked up and they had our credit card number on them. We had never given it to them.
I hope the internet credit card processor on the sites where I use my credit cards are staying on top of the latest resources for the protection of their customers. If businesses chose a reputable company to set up their credit card processing I expect these crimes would decrease. I prefer using my credit card as it is not safe either to be carrying large amounts of cash around.
