Say you are an employer or the head of a sports club, gym, library, educational institute. And you want to authenticate the entry of employees, members, visitors to your work premises.
You obviously do not wish to share your workspace with trespassers or irrelevant people. You only want authorized personnel to be given entry.
Now the question is—how to do it? How do you authorize these entries?
A. How to authorize entries
Here are a couple of ways to manage unwanted entries:
1. General identification cards
This is the most common way to authenticate entries. You simply need to design a general ID card for each member.
This ID card will have their details (such as name, designation, photo, etc.). And can be used at the entry gate.
Though it is still a common way to validate entries, it has many limitations.
The limited printing space of these ID cards allows you to print only limited details. And they’re even vulnerable to duplication.
For example—a person can simply get a photocopy of the card to put his own photo on it. And then use it to get entry into the premises.
And you certainly wouldn’t want this to happen.
2. Hard Tokens
Hard tokens are a great way to authenticate entry and manage security. And there are various hard tokens that organizations use.
For example—smart cards. Each of these cards has a seed code which, once scanned, authenticates the entry.
Small tokens are yet another type of hard tokens. You need to install a token slot at the entry gate. And these tokens need to be inserted in it for the entry process.
However, there’s again a problem. Hard tokens need you to install setup and are expensive. In fact, people also need to carry tokens every day which is yet another drawback.
3. Biometric verification
It is one of the best authentication methods. It’s fast and has a great user experience.
You can practice it in various ways—via fingerprints scan, iris scan, facial recognition, and voice verification.
The probability of forge entries through Biometrics is equal to negligible. Yet here’s a crunch!
The method may prove to be a bit expensive. There are installation costs, maintenance costs and, then, repair costs.
Plus, the accuracy of recognition can sometimes face glitches.
4. ID Card with QR Code
You’ve probably seen them on newspapers, flyers, and brochures for promotions. But that’s not their only use case. They’re also being used for use cases such as security, education, and payments.
And they can help you with authenticating entries as well.
Here’s how it will work:
Each ID card has a QR Code on it. This QR Code takes you to the cardholder’s encoded details. And you don’t even need you to worry about tampering. Keep reading to know how.
Here are various ways you can use this system:
1. Via a Website URL QR Code
You can enter each employee’s details (such as name, designation, contact number, and photo) on your own website.
And then use the link to these details to create a Website URL QR Code for each one of them. Then add these QR Codes to their respective ID cards.
When scanned, it will show the encoded link and will take the end-user to the cardholder’s details on your own website.
These details can include both text-based and multimedia details (such as a picture).
Security personnel at the entry gate can then scan this QR Code. If the details on card match with those on the website, the cardholder gets the entry. That simple.
No need to worry about card tampering anymore.
2. Via Simple text QR Code
A simple Text QR Code, when scanned, shows you the encoded data.
You simply need to add cardholder’s details while creating the QR Code. For example—name, designation, contact number, and address.
When scanned, the QR Code will show these details on the security personnel’s handheld device (or smartphone).
3. Via a Serial Code QR Code
A Serial Code QR Code, when scanned, shows you a serial code.
Not sure how it would work? Well, you can get this serial code to link to the cardholder’s detail in your own database (just like a Website URL QR Code).
If these details match with the printed ones, the entry will then be authenticated.
You now know how QR Codes can be used to authenticate entries. Simply decide which one you’d like to go ahead with.
They do not only solve the problem of limited print space but are also cost-effective.
Also, unlike a general identity card, a QR Code ID Card is unlikely to be duplicated. Especially the custom-designed one.
QR Codes do not need you to install any cost-intensive setup. All that you need is—an ID card with QR Code for each employee. And a smartphone app to scan the QR Code which will fetch the serial code and retrieve details from the database.
B. How to create an ID Card with a QR Code
You’ll first have to design a template for ID Card design. So, design a common template for all the employees and leave placeholders for information such as name, designation, and QR Code.
Once you design the template, decide which QR Code do you want to create. That means—Website URL, Simple Text, or Serial Code QR Code.
Say you’ve decided which QR Code you’d go ahead with. The next step is—to create QR Codes.
And you’d need a QR Code generator to do that. But here’s a problem.
You’d need QR Codes in large numbers (maybe in hundreds). Would you create them one-by-one?
Don’t worry. You can actually create them together in bulk. How? Using an online Bulk QR Code generator.
C. How to create QR Codes in bulk
You can find a bulk QR Code generator online. Using QR Batch for a demo, here’s a broad outline of the process to create multiple QR Codes together:
1. Create a spreadsheet with all the details to be encoded in the QR Codes
Note that the first column should be ‘Filename’ and second column onwards, data varies according to the type of QR Codes to be created. Here’s how you can create the spreadsheet.
2. Download the spreadsheet in CSV, XLS, or XLSX format
3. Go to QR Batch and select the type of batch that you need (website URL, serial code, vcard, or simple text)
4. Upload the spreadsheet
5. Review the data
6. Add a design to QR Code batch (you can customize the QR Code by adding your company’s logo and colors to it)
7. Make payment
8. Download your batch of QR Codes
To know the detailed process to create QR Codes in bulk, refer to this detailed guide.
That’s it. You now know how to create an ID card with a QR Code.
Note that you must ensure the color of the ID card’s background is in contrast to that of the QR Code.
That means if the background is light colored, QR Code should be dark and vice-versa.
This makes sure that the QR Code remains scannable.
You’re now ready to create ID card with QR Codes. QR Codes are not just a cost-effective way to authenticate entries but are also user-friendly.
So, employers, you already have the list of various authentication methods. Follow the best-suited one to attain maximum entry authentication and security at your premises.
