Systems and methods for securely storing digital assets using a secure portal are disclosed. Using an isolated computer within an electronic isolation chamber, a plurality of digital asset accounts may be generated, and one or more private keys and a digital asset account identifier corresponding to each of the digital asset accounts may be obtained. A respective reference identifier may be associated with each digital asset account. At least one of the one or more private keys corresponding to each digital asset account may be divided into a plurality of private key segments and written to a card along with the respective reference identifier to create sets of collated cards, wherein each set comprises cards corresponding to different private keys.

Systems and methods for peer-to-peer money transfers are disclosed. The system may allow senders to transmit money transfers to receivers. The system may receive a money transfer request from the sender comprising the designated receiver, a money transfer amount, and a sender transaction account. The system may generate a receiver transaction account associated with the designated receiver, wherein the receiver transaction account comprises the money transfer amount. The system may provide the receiver access to the receiver transaction account using different channels, including by providing a digital transaction instrument or a physical transaction instrument.

One embodiment of the invention includes a system comprising: a personal digital key and a computer readable medium that is accessible when authenticated by the personal digital key.

A payer transaction device enables secure offline transactions using a secure element providing a secure payer account database, a secure ledger database, and a wallet application. While the payer transaction device is not connected to the Internet, the wallet application receives a payee identifier and a transaction amount and verifies that the transaction amount is less than an available payer account balance in the secure payer account database. In response, the wallet application creates a digital token that allocates the transaction amount from the payer account balance to the payee identifier, and records the digital token in a payer secure ledger in the secure ledger database, which reduces the available payer account balance by the transaction amount. The wallet application then transfers the digital token to a payee transaction device over a peer-to-peer wireless connection and, subsequently, the digital token is synchronized with a ledger tracking system through the Internet.

Systems and methods disclosed provide ways for Health Care Professionals (HCPs) to be involved in initial patient system set up so that the data received is truly transformative, such that the patient not just understands what all the various numbers mean but also how the data can be used. For example, in one implementation, a CGM device is configured for use by a HCP, and includes a housing and a circuit configured to receive a signal from a transmitter coupled to an indwelling glucose sensor. A calibration module converts the received signal into clinical units. A user interface is provided that is configured to display a measured glucose concentration in the clinical units. The user interface is further configured to receive input data about a patient level, where the input data about the patient level causes the device to operate in a mode appropriate to the patient level.

Systems and methods for peer-to-peer money transfers are disclosed. The system may allow senders to transmit money transfers to receivers. The system may receive a money transfer request from the sender comprising the designated receiver, a money transfer amount, and a sender transaction account. The system may deduct the money transfer amount from the sender transaction account. The system may generate a receiver transaction account associated with the designated receiver, wherein the receiver transaction account comprises the money transfer amount. The system may provide the receiver access to the receiver transaction account using different channels, including by providing a digital transaction instrument or a physical transaction instrument.
