+This modules extends the Point of sale functionnalies to add a warning
+if confirming an order generate a cashback.
+
+By default, if the payment lines of an Odoo PoS order generate Change,
+the journal for the change will be the Cash journal.
+That is ok if the original payment line is a Cash payment, but if it's
+a payment by credit card, check, meal voucher, etc. confirming the
+transaction will generate a cashback.
+
+This module simply add a message in such case.

+
+
+**Note** : The cashback is an operation that consists,
+for a merchant to collect more money in check, credit card, etc.
+than the amount of the sale and give change in cash.
