What's Safest: Credit Cards, Debit Cards, Cash, or Checks?

I have been researching on respected and trustworthy sources on this issue. Which indeed is the safest way of paying your purchases online? Should you by your credit card. debit card, send cash or check?

For a good answer I turn again to my favorite authority - http://www.privacyrights.org/ - a non-profit consumer information and advocacy organization.

What I learned I pass it to you. Accordingly to my source, the credit card is still the safest way to shop on the Internet. Here's why:

1. Should anything go wrong with the transaction, you are covered by the Federal Fair Credit Billing Act. This means that you can dispute charges made on your credit card and you can withhold payments as well, during such dispute.
2. If the credit investigation determines that your credit card was used without your authorization, you will be responsible only for the first $50.00 in charges and rarely will you be asked to pay such charge.
3. Shopping by check or money order leaves you vulnerable to bank fraud and does not give you any protection should you encounter problems with the order/transaction.
4. Debit cards likewise exposes your bank account to thieves and a checking account can be wiped out in minutes. A debit card or a check card or an ATM card is NOT A TRUE CREDIT CARD and therefore does not give you any protection in case of problems with your online purchase.

Recommendations:

1. Dedicate one credit card for online payments alone. This will make it easier to detect wrongful credit charges.
2. Check your credit card bills carefully after purchasing online. Make sure there are no charges for purchases you did not make. Should you find one, contact the credit card company immediately and file a dispute claim.
3. Try to limit your online shopping to sites that you have bought from before and which you have not experienced any suspicious transactions with.
