Resumen de: US2025148438A1
A network-based service creates a smart contract on a blockchain on behalf of a user who has a loan or a subscription that requires installment payments be collected by a provider from the user and provided to creditor of the loan or subscription. The smart contract associates a default account of the user with a first access token and non-default registered other accounts of the user with a second access token. The smart contract when presented with the access tokens from a provider determines whether the payment due can be satisfied from a current balance of the default account and if so, transfers the payment from the default account to the provider. If the default lacks sufficient funds for the payment, the smart contract proportions the amounts taken from each of the accounts to reach the amount due and transfers the amount due to the provider.

A system, method and process for product authentication and verification using Near Field Communication (NFC) technology, blockchain technology (Hyperledger), and cryptography. A unique product identifier is generated for a unique individual product, incorporated into a data structure, and the data structure is recorded to a blockchain initiating an immutable record for the unique product identifier. An NFC tag is encoded with a tap-unique URL comprising the unique product identifier and a cryptographic output and affixed to the product. Each time the tag is tapped by a proximity coupling device, a web client operating on the proximity coupling device opens the URL whereupon the tag is verified using a cryptographic verification process and generating a verification result. The verification result is recorded on the blockchain ledger for the unique product identifier, thereby creating an immutable record of each tap interaction result.
