Abu Dhabi, capital of the UAE, has a fully integrated Digital system which lets any resident, every visitor to, every commercial business (importers and exporters), and every other Government Department access every Government department. ​

They can do this via a web-portal or via a free app which can be downloaded to any smart phone.​
