An electronic, handheld transaction register device for indicating an account balance of a bank, or other, account that permits two or more parties to make transactions in the account independent of one another. When a transaction is made, a synchronization signal is generated and sent to the electronic, handheld transaction register device. Responsive to detection of the synchronization signal, a local transaction register is adjusted to reconcile the account. A display is generated, providing a user of the device with an up-to-date and accurate indication of the account balance.
