Meet TokenCard™: A depositless Ethereum token-based debit card & platform with 3 simple elements

• The Token™ Contract Wallet: secures users' assets and enforces user-set spending and security parameters.
• Your physical TokenCard™: connects your Contract Wallet to the VISA® network — enabling online payments, PoS transactions and ATM withdrawals, using ERC20 tokens in the Token™ Contract Wallet.
• The mobile Token App: neatly unifies the process, offering a clean, intuitive experience and empowering users to finally go bankless, wherever they are.
