Various embodiments are directed to applying, via contactless card authentication, one or more restrictions to a virtual card number and generating the card number for use by a recipient. The one or more restrictions may be specifically personalized to the recipient and may include, for example, a merchant restriction, an amount restriction, a time period restriction, or a location restriction. The generated virtual card number along with the applied one or more restrictions may be consumed in various ways, such as writing the number to a blank card, transmitting the number directly to the recipient's computing device, etc., all via near-field communication.

A voice broadcast method includes: acquiring at least one piece of voice information; delivering the at least one piece of voice information to a voice broadcast device, wherein, the at least one piece of voice information includes voice identification information and a voice content; determining a first voice content to be broadcast by the voice broadcast device, wherein the first voice content is included in the at least one piece of voice information stored at the voice broadcast device; and sending, to the voice broadcast device, a first voice identification information corresponding to the first voice content, wherein the first voice identification information is used by the voice broadcast device to obtain the first voice content stored at the voice broadcast device, and to broadcast the first voice content when a preset voice broadcast condition is met.

An example transaction analysis platform is described herein. The transaction analysis platform may analyze an audio signal to determine whether a user is associated with a transaction. The transaction analysis platform may determine that a tone of the audio signal is a transaction tone associated with the transaction. The transaction analysis platform may process, based on detecting the transaction tone, the audio signal to identify a set of tones associated with the transaction. The transaction analysis platform may generate, based on a quantity of the set of tones, transaction information associated with the transaction, wherein the transaction information identifies a quantity of items associated with the transaction, wherein the quantity of items corresponds to the quantity of the set of tones. The transaction analysis platform may perform an action associated with the transaction information and a transaction account of the user.

A user registers for an account with an account management system, configures account settings to permit the account management system to receive user computing device data from a user computing device associated with the user, and logs into the account via the user computing device. The account management system receives a user voice purchase command and determines a purchase command context based on the received user computing device data. The account management system identifies a product that the user desires to purchase based on the purchase command context and directs the user computing device web browser to a merchant website to set up a transaction for the identified product.

A method for paying in a motor vehicle having a transaction device involves providing transaction data relating to the payment to the payment transmitter. The transaction data including a receiver address of a payment receiver, a payment amount, a transmitter address of a payment transmitter located in the motor vehicle, and a private key belonging to the transmitter address. The provided transaction data is entered into the transaction device. The entered receiver address is transmitted to the payment receiver, which authenticates the transmitted receiver address. Only if the authenticated receiver address is classified as authentic does the method proceed. This involves signaling the successful authentication of the receiver address to the payment transmitter and transmitting the entered transaction data entered to the cryptocurrency computer network for carrying out the payment. Accordingly, a transaction compiled from the transaction data is entered into at least one account book of the cryptocurrency computer network. A transaction status relating to the entry of the transaction is signaled to the payment transmitter.

A method of providing blockchain wireless services in a controlled environment is provided. The method comprises a wireless communication device associated with an inmate of a controlled environment receiving one of a voice and video call from a device external to the controlled environment. The method further comprises the device placing the received call into a hold state and sending a request for validation of the call via a blockchain, the request identifying at least parties to the call. The method further comprises the device, upon receipt of validation, removing the call from the hold state; and enabling at least one of voice and video functionality for the parties. The method further comprises the wireless communication device sending the request for validation to a telecommunications server and the server conducting real time monitoring of the call. The method further comprises the device continuously recording the call.

The invention provides systems, methods and computer program products for secure electronic payment transactions based on voice generated currency tokens. The invention comprises implementing at a voice currency platform server, the steps of (i) receiving from a payor terminal device a request for generation of a voice currency token, (ii) performing voice based biometric authentication by matching the voice data received from the payor terminal device against one or more voice based biometric templates associated with the payor voice currency platform account, (iii) performing speech analysis to extract at least the currency amount identified within the voice data received from the payor terminal device and (iv) generating an encrypted voice currency token.

Apparatus and methods are provided for a smart card which enables users to initiate a transaction or money transfer using voice commands. The apparatus and methods may include a smart card. The smart card may be responsive to voice commands and support electronic communication with a payment network. The smart card may include a housing, a network interface controller including a wireless communication interface, a voice controller, an active near-field communication chip, a microprocessor, a battery and/or an activation button. The smart card may also include executable instructions stored in a non-transitory memory, that when run by the microprocessor, detect and capture a first audio message via the voice controller and perform speaker-dependent speech recognition on the captured audio message to identify whether or not an authorized user of the smart card generated the audio message.
