Atala Scan

A company I am working with was hired to by IOHK, a company behind Cardano protocol to develop a mobile app that allows users to verify the authenticity and origin of a product by scanning an NFC chip attached to the product and a backoffice module for producers and brands to batch stamp products on the Cardano blockchain which is used as a database of stamped proofs of authenticity.

My job was to redesign the mobile application to improve the user experience of the user and give the UI a more modern look. Additionally, I had to improve the user experience of brands and producers that are chipping their products and importing them into the system and blockchain.

Mobile application

Main entry point for users through which they are able to scan products in order to check their authenticity via NFC reader after which they are presented with the authenticity status of the scanned product.

Since the application already had a design, I started with usability testing. By using the Affinity mapping method to organize and prioritize user feedback I recognized that the main issue users had is that there were no clear instructions on how to verify the authenticity and that the app had a registration/login process for no apparent purpose. The second one is a bigger issue having in mind that this was a web3 project.

The design process involved removing the registration process entirely, adding clear instructions for the user on every screen, and redesigning the product display pages so that they look clean no matter the format the brands use when uploading pictures of products. The latter required in-depth instructions and collaboration with the development team. Additionally, I gave the application a design that gave a techy vibe because of its blockchain background but also kept the glamour of the high-end products that are stamped by the brands.

Producer backoffice

Application developed for producers and brands so that they can stamp batches of their products on the Cardano blockchain. This gives producers ultimate confidence that the products they stamped on blockchain will remain intact.

The challenge was to allow brands to assign ranges of UID and CMAC to a product for which they further need to assign attributes such as a picture category and various other attributes based on the product category. On the software design side, it included a simple dashboard and a smart dialogue with a clean use comes first design. A large UX problem was solved by arranging with a chip manufacturer to label packages with the ranges of CMACs. Sometimes major UX improvements don't require expensive software solutions.
