QR code authentication

This QR code is a security measure that verifies the user’s identity before logging into their account.

Even some websites and online platforms today have an in-app QR code generation, which creates a specialized that users need to scan using their phones before gaining access to their accounts.

The use of a contactless payment QR code, for example, ensures that payments are made to the correct merchants without having to key in their details and double-check if the receiving number is correct. 

However, note that QR codes aren’t a replacement for usernames and passwords; online platforms still need these details to verify that you’re the owner of the account.

How QR code authentication works

Many online platforms use QR codes to grant users desktop or web access to their accounts. It is most common for web messaging apps, including Telegram, WhatsApp, WeChat, and Viber.

  1. Upon opening Viber on your computer for the first time, a page prompt for authentication and instructions is displayed on the screen.
  2. Open your Viber app on your phone.
  3. Tap the menu icon on the scan.
  4. Scroll down to the QR code reader.
  5. Scan the code on the screen to gain access to your account.

While these steps only apply to Viber alone, almost all platforms share the same sequence. You may try these steps with other apps to confirm.

Grant online banking and e-commerce access

Banking apps and e-commerce platforms can greatly benefit from QR code authentication. Every activity from these apps can cost you a lot of money, so you must be able to take control of your transactions.

Each time you make a purchase, transfer money, pay bills, or even change information, authentication ensures your identity is verified and your personal data won’t be compromised.

QR code verification

Purchasing counterfeits can be particularly dangerous for certain products, such as food, medicine, cosmetics, and electronics. 

That’s why manufacturers of these products are very particular when advising customers to verify the authenticity of their purchases.

A QR code placed on the product packaging may lead customers to the brand’s website, which verifies its authenticity. To prevent counterfeiting these QR codes, most brands use them as product seals.

Along with an authenticity certificate, scanning the product packaging QR code can also reveal the serial numbers, manufacturing date, country of origin, and other related information.

Improve healthcare data handling and access

Medical QR code

Healthcare information and patient data must be handled with utmost confidentiality, with only eligible healthcare professionals able to access these records.  Here’s where QR codes in healthcare and QR code verification come in.

QR codes allow better handling and management of electronic health records (EHR), which contain medical history, medications, and physician visits.

To access these records, healthcare professionals must scan the QR code to verify their identities; only eligible medical staff should have access to EHR.

Improving the handling and access of healthcare data and patient information can be used by medical personnel to provide you with care that best matches your health situation. 

It is especially crucial when you may need advanced care and emergency surgery, among others.

Ticket QR code for authentication online

Ticket QR code

The events management industry can use QR codes as authentication tools to ensure that only paying attendees can enter the venue. This prevents fraud and eliminates the need to print physical tickets.

Once attendees make a purchase on the ticketing website, they receive an email containing a  QR code. 

This serves as their e-ticket, which they can present before entering the venue. An usher scans this QR code to verify if their ticket is valid for the event.

These QR codes can only be scanned using a specialized authentication scanner online. Once scanned, they will immediately become invalid to avoid double entry and other fraudulent activities.

Another great benefit of a QR code for events is that it allows the events management team to monitor attendance, track visitor activities, and track the availability of seats.

Create a secure and well-connected enterprise systems

Businesses can use QR codes to allow key employees access to crucial internal systems and applications. Before they can access these systems, they need to scan the QR code authentication to log in to corporate portals.

Subsequently, this corporate portal grants you access to these internal systems and platforms. 

Moreover, the QR codes can be used to give each employee specific labels of authorization based on how likely they will use these systems. You can even enhance into a QR code with password, so only specific persons can access it.

For example, the admin department can find, edit, and approve pay increases and adjustments on a separate payroll system. 

On the other hand, the finance department can disapprove of these increases and leave comments but can’t edit information in the system, and so can the rest of the department heads.

This way, only employees involved can actually see related information, creating a well-connected secure system. However, management should also practice QR code security as well to protect their employees.
