How to create tamper-proof identity cards using QR code and blockchain-based technology?

tamper-proof identity cards


Nowadays, QR codes have become quite common, and anyone who engages in online transactions or document exchange can vouch for their utility in ensuring safety and security in these transactions. Quick response codes can be used in many different industries and fields, and they fit in with most.

Using QR code to manufacture ID cards.

Recently, Identity cards issued by many institutions also use this technology to authenticate entries of their employees. It has become almost like a race for top companies to include the most recent technology in their security procedure, and nowadays, this technology is QR codes. The code embedded on the Id card will send the reader to the encoded details of the cardholder. There are a few ways in which this can be done.

  • The first way is to do it via a simple text QR code. Once scanned, this simple text QR code will reveal encoded data about the cardholder previously added while creating the code. This code will disclose this information to the security personnel on their handheld device or smartphone, and they can then match it against the website data about the same employee.
  • The second is via a website URL QR code. Here the employer may add employee details like name, contact information, designation and photo on their website. The link to these details can be then used to create a unique QR code for each of them, and this QR code can then be added to their identity cards. Scanning will reveal an encoded link and take the user to the card holder’s details on the website. Entry will be given only if the information on the card matches the information on the website.
  • Finally, the third way is to do it via a serial code QR code. This means that when scanned, this kind of QR code will reveal a serial code, and this serial code can be linked to the card holder’s details in the employers’ database. In a way, it is very similar to the website URL QR code. When the details match with the printed ones, entry can be authenticated and allowed.

Using QR codes for identity cards is the most intelligent decision- not only does it solve the issue of space, but it also makes the document completely tamper-proof. Duplication isn’t possible at all. By dealing with limited print space, this solution also saves a lot of money for the company in question. There is no need to install any set-up which is cost-intensive. All needed is an ID card with an embedded QR code and a simple device (like a smartphone) to scan this.

How to create a QR code for an identity card?

  1. First things first, you need to design a template for the overall design of the identity card. Of course, the template needs to be shared with all employees. Leave space for information like name, designation, photo and the QR code on the card.
  2. Once the template is designed, decide which QR code you want to create. Choose one out of the options mentioned above.
  3. Once the type of code is decided, the next step is to create the code. For this step, a QR code generator is needed.
  4. For institutions that need to create QR codes in bulk, there is the option of using an online Bulk code generator.

How to create QR codes in bulk for people in your organisation?

  1. Starting with finding a bulk QR code generator online, the first step is to create a spreadsheet with all of the details which are to be encoded within the codes.
  2. Creating a spreadsheet includes the following steps: a. Downloading the spreadsheet in CSV, XLSX or XLS format.b. From ‘QR Batch’ selecting the type of batch you need, from website URL, serial code, or simple text. c. Uploading the spreadsheet. This is where the most work gets done. When you upload your employees’ details to the QR code generator website, they compile them and make them into compressed codes without you having to move a limb. d. Reviewing the data- might seem unimportant, but don’t skip this step. e. Adding the design to the batch. Here the QR code can be customised by adding different colours and even the company logo. f. Making the payment. Usually, QR code generators accept online payments. Thus the entire process can be dealt with without physically contacting people on either side. g. Downloading the batch of QR codes you just created. h. Ensure that the customisations make it easier to scan/read the code and not difficult- for instance, in choosing a colour, ensure that it stands in contrast to the background.

Conclusion: How to read QR codes on identity cards?

Reading QR codes is way more straightforward than reading Bar codes or other more traditional ways of identification. Previously, it was almost too easy to replicate identity cards and impersonate them as an institution employee. Today, it is becoming more and more challenging to pull off Identity theft because of how biometrics are being used and because some new and improved technology has made it almost impossible for fraudsters to hack into the systems.

Reading QR codes is as simple as opening the camera/scanner on one’s smartphone and placing it near the code. It’s a skill that requires minimal or no training for security personnel to adopt in their daily lives. QR codes can be read successfully even after incurring 30% damage, unlike bar codes. So overall, being cost-effective, almost damage averse and user friendly for both the institution and the employees, QR codes are the new best way to deal with identity authentication.
