A.How can QR Codes be used in the authentication

Here are some ways you can use QR Codes to prevent forgery:

1. Certificate authentication

You would have come across certificates (academic degrees or even licenses) getting duplicated. And it is very hard for a layman to understand the difference between an authentic certificate and a forged copy.

But QR Codes are up for the game. How? If you issue certificates to your students, customers, or other concerned stakeholders, you can add a QR Code to them. This QR Code can link to all the details on the certificate on your own website or database.

When the end-user scans the QR Code, he will be able to see all the details on the web link. And since the details will be hosted on your information system, it will not be possible for one to duplicate the certificate. Exciting, right?

2. Confidential document sharing

It is common in business to have confidential documents. And in such cases, you’d want only authorized personnel to be able to access them. 

Here, a password-protected QR Code can help you out. It helps you share the content encoded in QR Codes (text, document, or even a website URL) with only the people you want. 

You can enter a password while creating the QR Code and share it with the required personnel. When they scan the QR Code, they’ll be prompted to enter the password. Only once they do it, they’ll be able to see the encoded content.

3. Product verification

The fake copies of products are a common issue across industries. From pharmaceuticals to apparel, it concerns everyone. It can not only result in loss of revenue but also put your brand image at risk.

In such cases, QR Code gets you covered. Just like certificates, you can add a QR Code to the product packagings. When customers scan this QR Code, they’ll be able to verify the authenticity of the product and differentiate it from a fake copy easily. 

4. Vehicular authentication

With increasing traffic on roads, quick and reliable vehicular verification has become a challenge for city admins.

And many of them are using QR Codes to do the same already. Here, a QR Code is placed on the vehicle which can then be scanned to verify its status. It is especially helpful in case of an accident or a theft.

5. Laboratory reports

Laboratories issue health certificates all through the day. And amidst the pandemic, it has become important to verify the report’s authenticity to curb disease spread. QR Codes offer a seamless and effective way to do the job here.

6. Visitor management or employee verification

You probably have seen QR Codes on visitor passes and employee ID cards. They are used to help verify the authenticity of the personnel for entry into the premises. 

Here’s a detailed guide on how it can be done.

B. Popular Use-Cases of QR Codes for authentication services

There are a lot of organizations using QR Codes for authentication services already. Here are some of them:

1. CBD products

Various states across the world have made it mandatory to print QR Codes on CBD products for authentication purposes. 

For example, Florida has mandated that all legal CBD products must be distributed and sold with a label. This label needs to have a barcode or a QR Code linking to the Certificate of Analysis (COA).
