New Online Banking Card Readers: How Do They Work

Since the late 2000s, online banking card readers have been available, adding an added degree of security to regular online authentication. Researchers investigate how they operate and whether they are truly secure.

What do tabbed browsing and online banking have in common? “How could Anyone ever survive without this?” people will wonder once users start using either.

Responsible personal finance in today’s world nearly demands the usage of online banking. If people haven’t switched to internet banking yet, know that there are a slew of benefits, including various convenience features and the highest savings interest rates.

Is online banking, however, secure? That is the most common question, and the answer is, for the most part, yes, online banking is secure enough, especially when using online banking card readers.

What Is Online Banking Card Readers?

A card machine is also known as a card reader. It allows customers to swiftly and conveniently process card payments in their business.

A PDQ machine, a chip and PIN machine, or a card terminal are all terms that have been used to describe it. However, they all do the same thing: they allow users to accept safe and secure card payments.

How Online Banking Card Readers Work?

Since the late 2000s, online banking card readers have successfully added an extra layer of protection to traditional online authentication.

These readers are most popular in the United Kingdom, although they are also becoming popular in other countries.

An online bank portal will often require a login and password. One can also add a security image to personal account to avoid falling prey to angler phishing or other scams, as well as a security question in case their password is stolen.

The issue is that all of these methods of authentication are digital. Over the Internet, they can be cracked, intercepted, or brute-forced. Wouldn’t it be fantastic if authentication had a tangibility component to genuinely validate their identity?

As a result, some banks require a card reader in order to do online banking. This is how it works:

  • A unique code is required by each online banking website.
  • Ones card should be inserted into the reader.
  • In the reader, enter ones account PIN.
  • A one-time code is generated by the reader.
  • Copy the code and paste it into the website. Done!

These card readers aren’t always required, so they’re not as inconvenient as they appear. The reader is usually simply required to do the following:

Potential Security Issues With Online Banking Card Readers

The first thing to know (which may help people relax) is that these card readers do not keep any of ones personal information on the device. When simply insert ones card or punch in the PIN, users can rest certain that the reader will not keep any of that information.

For those who are concerned about mobile online banking, this is good news. By requiring a card reader for particular operations, users are essentially compelled to have the card reader with them at all times if they want to execute such actions while on the road.

Some card readers are universal, which means they can read and create codes for any EMV card that is compatible with the reader’s online bank. In that way, anyone might use another person’s card reader as needed, and their reader would not keep any information about personal account or card.

Online Banking Card Readers: Safe Or Not?

Using an online banking card reader is, at the end of the day, a trade-off. Because some capabilities are limited if users don’t have the reader with oneself, they are giving up a little convenience in exchange for increased security. However, that extra layer of security isn’t ideal.

Some banks, but not all, require users to utilize one of these readers. If the risk of a card reader bothers people, and the bank forces them to use one,  they will have no choice but to switch banks.


Given the present climate, card readers are more vital than ever, so it’s critical for businesses to understand how they work in order to stay ahead of the game.

Payment methods, systems, and processes will continue to evolve, whether people are a first-time business owner or a seasoned expert.

If their company is seeking to grow, some of the best card machines for small businesses or even some of the more recent card reader apps might be worth checking into.
