Embedded NFC tag and companion NumiSalis smartphone apps mean you can have confidence the coins are legitimate, correctly charged with bitcoin and you don't have to rely on FirstBits.
All coins are sold at a 10% mint margin. The lowest in the industry. The NumiSalis companion app shows the realtime NumiSalis value to bolster the trade value.
With coins valued as small as $1 in bitcoin you will be able to use NumiSalis coins for day to day purchases.
