While most hardware wallet manufacturers sell a device that stores and signs cryptocurrency transactions, Vaulttel has released a different kind of wallet. The Vaulttel Intellichip card is a wallet that fits into a SIM card tray and allows users to store and access their private keys. According to the company, the wallet surpasses the competition because it includes biometric authentication, the ability to limit access to wallet to a particular geo fence, and device locks so the user can assign the wallet down to a particular phone. In order to use the application, users are required to utilize a chip and chip dongle. Vaulttel also allows users to back up wallets with additional Intellichip cards.
