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.

The invention relates to a system for the acquisition of electronic services and/or products using electronic messages, comprising: at least a plurality of devices for receiving/sending instructions, wherein each of the devices for receiving/sending instructions is for generating an instruction of the selection carried out by an initial user of said system and sending same to an instruction-processing server for the processing thereof; an instruction-processing server for receiving and processing the selection instruction of the initial user in order to generate an assigning instruction and send same to an assigning server; an assigning server for receiving and processing the assigning instruction of the instruction-processing server, generating a sending instruction that is dealt with by the electronic message-sending device; a plurality of the final user devices, wherein each of the devices is managed by a final user, which receives an electronic message from the electronic message-sending device; and a plurality of servers providing products and/or services, into which the final user inputs information contained in the electronic message received in the final user device via an access portal available in each of said servers providing products and/or services, in order to be able to have access to the requested electronic service and/or product.

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.

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.

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.
