Abstract: A system for managing a fund account includes providing a device such as a device resembling a traditional piggy bank which receives data signals when transactions are made within the fund account. The device preferably includes a visual indicator such as light-emitting diodes to indicate that such a transaction has been made. The device may also include an audible indicator to indicate that transactions have been made. The device preferably also displays savings goals and the status of the fund account in reaching that goal. A communication device such as a cellular phone may communicate with the device and send it such data signals, as well as communicate with a server to receive data signals when there is activity within the fund account.

Abstract: A method for transferring data, more particularly, over a low energy connection such as a Bluetooth Low Energy connection, includes dividing a source data into a plurality of data chunks, associating each data chunk with a verification data such as a checksum, transferring the data chunks and verifying that each data chunk was received without error, using the checksum. The method may also include providing a verification data for the source data, transferring it before and after all the data chunks, and verifying that all the data chunks and thus the entire source data was received.
