Our customer want to use 1 "Cash Keeper" ([login to view URL]) with 2 POS.
We need a software to make the link between the 2 POS software and the "Cash Keeper" machine.
This software will be installed on one of the point of sale machine.
The link between the POS and the bridge software will be by socket in JSON format.
The bridge software must handle the state of use of the cashkeeper machine. If already in use by the other POS, the call will be forbiden.
Once the other POS finished the operation, the second POS will be able to connect the bridge software & the CashKeeper.
The most important feature for us is to send the amount to charge and to receive the answer (OK and details, or ERROR and explanations)
