If you're International, this is what to do:

1. Email dani@blok.so with the subject "NFC Whitelisting"
2. Get yourself an NFC chip if you don't have one
3. In the body of the email include that NFC's serial ID
4. I'll take care of the rest

Pro Tip: Download the "NFC Tools" App from the app store (it's orange) to help you with #3.
