Prevent ATM Skimming with QR Codes: A Cardless Transaction

You are probably aware of ATM Skimming and PIN compromise. After all, they have been the most common ATM frauds in recent times.

So, to tackle it, there has been a slew of measures such as geo-blocking and anti-skimming devices. However, in spite of these, fraudsters find one way or the other to get your card details.

But what if there was a way to make it impossible for fraudsters to get card details? What if we removed the card altogether from the equation? This is possible by using cardless transactions and trusted devices that account holders carry with them all the time – their smartphones.

This even makes sense as it can act ​​as a second factor of authentication since most people always have their phones with them.

A. How do cardless ATM transactions work?

According to Chicago-based Wintrust Financial, a cardless transaction takes only 8 seconds compared to a card transaction that takes an average of 47 seconds. This is how the process works:

  • When you are at the ATM, open your bank’s app on your smartphone (most require you to enter a four-digit code)
  • Open the QR Code scanner feature in the app
  • Choose the Cashless Withdrawal option on the ATM screen
  • Scan the QR Code that the ATM will display on its screen for verification (the QR Code changes for every transaction just like how the WhatsApp Web QR Code works)
  • Once done, your identity would be verified 
  • You can now go ahead and withdraw the money

That’s it. That’s how simple it is. So instead of using a magnetic-tape card and a PIN, you simply use your smartphone app to authenticate yourself.

A. QR API and its benefits

As mentioned above, QR Codes can help you prevent ATM skimming altogether. And to generate them, you need an automated QR Code generator.

This is where QR Code API can help you out. It allows you to auto-generate QR Codes programmatically.

But before proceeding ahead, you should be familiar with its benefits. Yeah, that’s right. QR Code API offers various benefits while helping you auto-generate QR Codes programmatically in real-time. Here are some of them:

1. Provides a seamless automated process

Want to auto-generate QR Codes without even sweating a single drop? Here, QR Code API helps you auto-generate as many QR Codes as required. You simply need to integrate the API with your information system and that’s it. No manual intervention is required anymore.


2. Offers a personalized look

Since you are using QR Codes for your business, you may want them to look brandy too. You know the significance of branding after all.

This is a very simple and quick process. No hassle of waiting for long periods of time to get the job done.

C. How to set it up?

To set up cardless transactions via QR Codes, you will need the following:

1. A QR Code API service provider 

For ensuring secure transactions, you will need to update your ATM software. And to do that, you need a tool that allows you to automatically generate a QR Code for every transaction. That means QR Codes get changed for every transaction whenever the account holder chooses the option of cardless transactions. 

And QR Code API can help you out. It will allow you to generate QR Codes programmatically in real-life. And this QR Code can only be decoded using the scanner feature of the bank’s app.
