Qr code means quick response code. A Japanese automotive company Denso Wave developed it in 1994. It works somewhat similar to a barcode, but it is much faster as it proceeds the information in a couple of seconds.
Contrary to a barcode reader that one needs to read information embedded in barcodes, QR codes do not need specials devices, and one can access it by a smartphone camera. One can use a QR code in many ways, such as to show product details, track overall product delivery, track the documents, to show menu to customers in hotels/restaurants, for accessing social media platforms, to get access to any webinar or any website or link, and even to transfer money etc.
Blockchain-Based QR Codes
Experts are making blockchain-encrypted QR codes in their sectors to bring a better level of security and safety. Over the last decade, you might have seen QR codes grow in popularity across different applications away from their original uses in manufacturing, thanks to the massive ownership of camera smartphones with applications that could read the QR codes.
It headed to an explosion of its utility – in marketing, secure documents, and more. In the last year, it steeply further in popularity because of its use for contract tracing for covid-19 and is presently omnipresent.
During the same decade, blockchain technology has also risen in popularity for possible uses beyond its initial use in cryptocurrency bitcoin. Now professionals are looking at it actively for smart contracts, trade finance, education documents, and the medical field. In addition, they are talking about using it to secure confidential documents like certificates.
Blockchain-Based Secure QR codes
You can consider a blockchain secure QR code because it is tamper-proof and secure on the blockchain, just like the immutable ledger. Being a validator user, you can still validate the documents or data even if you are not part of the network, which is the need in the blockchain. The point is that verification is decentralized in the blockchain. Thus, secure QR codes combine the utmost of both worlds for you.
For example, you can quickly secure your confidential documents and data in a secure QR code. Once you put a secure QR code on any record or data, one can access it only if the hash value of the code matches with the hash value of the secure QR code on the blockchain network. Hence, there is no room for any tampering or fraud. One can quickly validate the documents and stay at peace. For your understanding, the prime elements of blockchain are like:
– Better security: it is with the use of hashing, encryption and cryptography
– Distributed ledger: each participant can see every transaction and validate and even keep a copy
– Immutability: one cannot change or alter anything in an unauthorized manner
– Decentralised: there is no one governing authority
– It is based on consensus procedures.
The Bottom Line
Blockchain technology is expanding, and secure QR codes permit you to use them in different use cases such as cheques, invoices, id cards, passports, school certificates, trade finance documents, vaccination certificates, covid19 test reports, etc. If you want to integrate QR code security into your business procedures and documents, you can talk to experts at ProofEasy.
