What are QR codes

QR code

QR codes are a type of matrix (2D) barcodes. The big difference with the older linear (1D) barcode is that it can contain hundreds of characters. Perfect for storing links or other digital data.

The QR code technology is freely licensed by DENSO WAVE and in the beginning designed for the Japanese automotive industry. Thanks to the fast readability and easy to recognize design we can nowadays find QR codes everywhere.

Secure QR code

Encrypt your data before it is stored. How it works? Simple, just click on the lock in the input field. After submitting we create a random key that we use to encrypt your data. The encryption we use is based on the Galois/Counter Mode, great for keeping your data secure. After the encryption we store your encrypted data in our database. The unique key is added to your QR tag and returned to you, without this key it is impossible to decrypt your data.


Why Optional?

Why we keep it optional? Well the thing about encrypting your tag is that the code will be slightly bigger, and since we try to keep the QR code as small as possible, we think it is up to you to decide to encrypt or not.

That's not all, we listed up the pros and cons for encryption:
