GoNow Technologies has developed a reprogrammable magnetic stripe card that communicates with an eWallet on a mobile phone via Near Field Communications (NFC). A single GoNow eWallet Card can be programmed to become any credit, debit, gift or loyalty card in an eWallet, thus eliminating the need to carry all those plastic payment cards. The GoNow eWallet Card may be integrated with any eWallet by means of an API, enabling eWallets to immediately work at all POS terminals without any changes to the existing payment infrastructure. Thus, an eWallet with the GoNow eWallet Card works at 100% of POS terminals, both contactless and magnetic stripe.
