Abstract: Systems and methods are provided for facilitating contactless payment using cloud-based wallet containing payment credentials (e.g. Visa, Mastercard, American Express) using a near field communication (NFC)-capable device and payment gateway servers. A user can use their existing payment card, herein referred to as a funding card, for contactless payments. A second payment card, herein referred to as a virtual card, is generated. The virtual card is associated with the funding card on a payment gateway server. The virtual card is used on a NFC-enabled mobile device. When a payment is initiated, the virtual card data is sent through the NFC system from a point of sale terminal. This information is sent to the payment gateway server, which retrieves the funding card to make the payment. The funding card, not the virtual card, is used to transfer the money to make payment.

Abstract: User accounts for blockchain technology are prone to security risks, such as account take-overs by malicious actors and lost or inaccessible wallets. A data access server system is herein provided to enable strong authentication credentials, such as FIDO2 public and private key pairs that adhere to Fast Identity Online (FIDO) protocols, to be used generate user account. The FIDO2 public key, also herein called a device authenticator public key, is embedded in a code script, and the code script is executed by the data access server system to verify the user using FIDO authentication. The data access server system also provides user tools to create credentials and associate one or more credentials with a blockchain user account. The user tools also enable rekeying of a blockchain user account with different credentials from another blockchain user account, with both accounts belonging to the same user.
