In the years when credit cards first appeared, it was mandatory to use them physically when shopping. But as technology and the internet developed, payment systems and payment methods also went through a number of changes.
We now sell our products over the internet, and we research the products we will buy in detail online. We can find the most suitable product at the most suitable price on the internet. So, over the internet, without having our card with us, we can shop with only the following details of the card:
Card Number
Expiry Date
CVV2 (the 3-digit number on the back of the card)
In order to do this, the relevant website must have a virtual POS integration and must support card transactions.
In transactions made with a card on a physical POS, we feel at ease because the transaction is approved by entering a PIN. So how do we enter our PIN in transactions made through a virtual POS? How is the security of purchases ensured? At this point, 3D Secure comes to our rescue.
In payments made with 3D Secure, a special 3D Secure transaction screen provided by the bank opens on the bank and user screen, and a verification code is sent by SMS to the mobile phone of the owner of the credit card used for the purchase, or special information known to no one but the cardholder is requested. In successful payments made this way, the bank assumes all responsibility in the event of any adverse situation. With 3D Secure, purchases made with a stolen credit card can easily be prevented. The reason is that the payment is completed by sending an SMS verification message to the cardholder’s phone.
In addition, with newly developing technologies, the rate of contactless payment has increased considerably. Contactless payment is a technology that relies on NFC (Near Field Communication) hardware, which has long been used in smartphones and has become increasingly important recently. This standard, which removes the need to carry a card and adds one more function to our phones that are with us 24/7, is not yet very widespread in our country, but it is becoming more widespread day by day.
In short, whether the transaction is made on a physical POS or through a virtual POS, we can get a successful authorization even if our card is not with us. There is only one condition: our mobile phone, which we forget even less often than our wallet these days, must be with us 🙂
