Methods, devices, and servers for as-needed update of a trusted list are provided herein. An electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The eSIM server evaluates the particular type and requests an eSIM of the particular type from a second eSIM server, which is not initially trusted by a secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device. The wireless device passes the policy update to the SE, for example, a universal integrated circuit card (UICC). The UICC updates the trusted list with an identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list. The eSIM is then installed on the UICC.

The present invention provides implementation and communication methods, an apparatus and a system of a virtual subscriber identity module. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. The embodiments of the present invention effectively solve a problem where an existing mobile operator network does not support the VSIM, and provide an effective and convenient operation scheme for an existing domestic or international roaming service.

A system and method are described for an Internet of Things (IoT) coin operated machine. For example, one embodiment of a system comprises: an Internet of Things (IoT) device comprising a local wireless communication interface to establish a local wireless communication link with one or more IoT hubs or client devices and a microcontroller unit (MCU) to execute program code; a secure communication module to establish a secure communication channel between the IoT device and an IoT service over the Internet using the local wireless communication link; a machine/coin acceptor interface comprising a first interface to communicatively couple the IoT device to a coin acceptor device and a second interface to communicatively couple the IoT device to a machine control unit to control operations of a coin operated machine, the machine/coin acceptor interface to receive signals from the coin acceptor device over the first interface when coins are inserted into the coin acceptor device and to transmit a signal to the machine control unit over the second interface to cause the coin operated machine to perform operations when a specified number of coins have been inserted; and the machine/coin acceptor interface to further transmit a signal to the machine control unit over the second interface to cause the coin operated machine to perform operations in response to a command transmitted from the IoT service to the IoT device through the secure communication channel.

A process for authorizing wireless service includes providing a generally rectangular flat form factor card having a first surface and opposing second surface. The process further includes providing a machine-readable activation code arranged on the first surface, wherein the machine-readable activation code is configured to authorize the wireless service when provided to a system associated with a wireless service provider, receiving the machine-readable activation code in a server, the machine-readable activation code being captured by a wireless device, and provisioning the wireless service to the wireless device from a wireless network when the machine-readable activation code is provided to the system associated with the wireless network.

A card reader includes a digital connector such as a Universal Serial Bus (USB) plug or an Apple Lightning plug. The digital connector includes a corresponding connector interface, which provides voltage to at least a card reader interface and an integrated circuit (IC) of the card reader. The card reader interface outputs an analog transaction information signal upon reading the card. The IC generates a digital version of the analog transaction information signal, encrypts the digital version, converts that into an analog audio signal. The audio signal can then be sent to the connector interface, which converts it into a digital signal such as a USB or Apple Lightning signal that is sent by the digital connector to a mobile device. Alternately, the audio signal can be sent to a microcontroller that converts the audio signal to a digital format such as USB, and then to the digital connector.
