Pairing FAQs
Do I need anything besides my phone?
Just the Vault Key Card and an NFC-capable phone with the Zypto App.
Are my keys ever exposed?
No. Keys are generated and held on the card; pairing never transmits them.
Can I pair more than one device?
Yes - pair the card with the devices you use, each over NFC.
