Abstract: The present disclosure relates to a cryptocurrency card for engaging in cryptocurrency transactions. In one example, a user has a user device and a card. The user device can generate a graphical user interface that includes transaction data associated with an account of the user with a service provider. The graphical user interface can include an option for linking one or more digital wallets to the card. In response to detecting a user selection of the option, the user device can interact with a computer system associated with the service provider to link a digital wallet to the card. Based on the link, the computer system can then use the digital wallet to execute cryptocurrency transactions initiated using the card. The computer system can also update the transaction data to describe the cryptocurrency transactions.

Abstract: Some examples described herein involve an interactive game system and virtual world for educating users about cryptocurrency. In one example, a system can generate a three-dimensional (3D) virtual world for a video game. The 3D virtual world can include game objects and a virtual avatar representing a user, where the virtual avatar is movable within the 3D virtual world to interact with the game objects. The system can detect an interaction between the virtual avatar and one of the game objects within the 3D virtual world and, in response to detecting the interaction, select a learning module. The system can select the learning module from among a group of learning modules based on the game object. The learning module can be configured to provide an educational tutorial to teach the user about cryptocurrency. The system can then execute the learning module to provide the educational tutorial to the user.

Abstract: The present disclosure relates to a graphical user interface and card system for engaging in cryptocurrency transactions. In one example, a system can provide a graphical user interface to a user. The graphical user interface can include transaction data and an option for linking a digital wallet to an account of the user. The system can detect a selection of the option and responsively link the digital wallet to the account. The system can also link a card to the digital wallet. Thereafter, the system can receive a request associated with the user using the card to engage in a cryptocurrency transaction. Based on the link between the card and the digital wallet, the system can determine that the digital wallet is to be used to execute the cryptocurrency transaction. The system can then use the digital wallet to execute the cryptocurrency transaction and update transaction data accordingly.

Abstract: A low noise clock oscillator in standard surface mount plastic or ceramic form. With the same soldering pads design such devices can be replace with a convention standard surface mount clock oscillator to reduce Electro-magnetic Interference or RFI (Radio Frequency Interference) without redesign of the main board. The oscillator is characterized by using a spectrum spread clock generator and a spread controller on an elevated platform to reduce common mode emission currents.

Abstract: A low noise clock oscillator in modular form to plug into a standard 14 or 8 pin DIP clock oscillator socket on the motherboard of a host device to retrofit the host device without redesign of the host device motherboard so that the host device can reduce its EMC emissions sufficiently to pass EMC emission tests. The oscillator is characterized by use of a spread spectrum clock generator, EMC filters between the clock generator and the Vcc, ground and clock bus coupling points to the motherboard and a single point ground connection to the motherboard. This oscillator module allows an easy retrofit to a host device that has already been designed to substantially lower EMC emissions that can be traced to the clock by as much as 20 dB without expensive, time consuming redesign efforts to add shielding, more grounds and possibly reroute the motherboard traces.
