Poker sites that accept 3D Secure are very secure and this is because 3D Secure has an added security measure that is adopted by VISA for debit and credit card transactions that are carried out online. This technology basically transfers liability of fraud from the credit card company to the user of the card. Any money lost due to insufficient utilization of this service is considered the user’s fault. However, it increases security of transactions if utilized appropriately.
3D Secure provides PIN protection for transactions made via VISA card online. The feature has to be present with the card for it to work. You should ask your bank if there are such arrangements for the card they issued you with. While making deposits at casinos that accept 3D Secure you will be prompted to key in your current PIN.
For this technology to be practical, you will have to keep your PIN a secret so that no one else can use your card to make deposits at 3D Secure poker sites. This feature is increasingly becoming mandatory for online transactions and thus you should consider activating it.
3D Secure casinos will still allow you to make deposits if 3D Secure is not activated. However, activating it will keep your account more secure from fraud.
