KeePassNFC

Work's grear. I had the same problem as some people. First time I wrote to the card it worked great, but second time I tried to write same card after I formated it app crashed everytime. I solved this by cleaning app's cache and formating and erasing card's memory. I did that with NFC tools. I don't know what exactly help, but maybe it will be useful for some else.

Doesn't work. It crashes everytime.

The screenshot shows a DropBox path, but there is no way in the app to open a file in DropBox. My KDBX file doesn't appear in the "recents" list, no matter what I try. [EDIT: Bumping this to 5 stars, as I finally figured out how to get a DropBox file open... in the Open From dialog, you need to click on the 3 dots at the right to change the settings, and turn on the option to show internal storage. Then you'll be able to navigate to the path your DropBox files are in.... \Android\Data\com.dropbox......]
