A method handling payment transactions in a system using mobile communication devices as stored value devices is disclosed. A transaction operations server receives multiple records of the transaction from the stored value device&#x2014;one via a communication channel through the telecommunication provider network, and another via an independent communication channel. The records are reconciled at the transaction server for transaction verification.

System and method of managing contactless payment transactions using a mobile communication device as a stored value device

A method and apparatus handling payment transactions in a system using mobile communication devices as stored value devices are disclosed. A transaction operations server receives multiple records of the transaction from the stored value device&#x2014;one via a communication channel through the telecommunication provider network, and another via an independent communication channel. The records are reconciled at the transaction server for transaction verification.

An architecture for an integrated circuit with in-circuit programming, allows for dynamically altering the in-circuit programming instruction set itself, as well as other software stored on the chip. The architecture is based on a microcontroller on an integrated circuit having two or more banks of embedded non-volatile memory arrays which store instructions, including an in-circuit programming instruction set. Using a control program stored on the device, the device interactively establishes an in-circuit programming exchange with a remote partner, and updates data and software, including the in-circuit programming instruction set, when needed. The processor and ICP code are responsive to an in-circuit programming update command to write a copy of the in-circuit programming set from a first memory array to a second memory array, and to cause the in-circuit programming to execute the in-circuit programming set from the second memory array to program the non-volatile memory cells of the first memory array with data from the external port.

System for logic extraction from a layout database

An architecture for an integrated circuit with in-circuit programming includes a microcontroller on an integrated circuit and one or more banks of non-volatile memory which store instructions, including an in-circuit programming (ICP) set of instructions. Using a control program stored on the device, the device interactively establishes an in-circuit programming exchange with a device external to the integrated circuit and uses data obtained in the exchange to update software for the microcontroller. Portions of the ICP code which are likely to change between different application environments are stored in reprogrammable flash memory cells. Other portions of the ICP code, which are not likely to change between different application environments, are stored in space-efficient mask ROM memory cells. In this way, the ICP system can be flexibly adapted to different application environments, while conserving on silicon area occupied the ICP system.
