LUKOIL e-DRN is a mobile app for suppliers of LUKOIL marine products. It is a tool to send the Delivery Receipt Notes (DRN) quickly and easily to LUKOIL once the products have been delivered. Scanning the QR code on the DRN will select the order that has just been delivered, then the app guides the user through saving a picture of the signed DRN and feeding the information (including optional comments) back to LUKOIL.
