The Next Level of Precious Metal Recycling for our World of Tomorrow - Efficiency and Transparency thanks to Digitalization. MAIREC is shaping the next generation of precious metal recycling by introducing "maiportal", a customer app which users can use to get detailed information about their orders including the status of currently ongoing deliveries. What quantity of which recycling material did I deliver to MAIREC last year or month? Which quantity of precious metals did we recycle together last quarter, how much revenue did we generate? What is the processing status of my latest delivery? Customers can now access this and much more information from anywhere, any time or can be informed automatically through tracking and push messages. Other useful functions are already in development, which will bring even more benefits to the usage of the portal. MAIREC is a company specialized in recycling precious metals like gold, silver, platinum, palladium and rhodium from materials such as automotive catalysts, electronic scrap, etc. We turn Scrap into Gold ... and Platinum and Palladium and Rhodium - For the next generation!

Verdict
The clearest difference is ads: maiportal at none against DF Auto's shown. DF Auto's advantage is update cadence (every 2 months vs every 5 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
