Be able to deduct balances if a certain amount was used at a physical location etc etc.
Is there anything out there like that?
I know magento has the native gift card standard online use. It would be nice to have physical cards as well that work for both.
What version of Magento are you on? Only Magento EE supports gift cards and you would then need a POS that ties directly into Magento to update the gift card $ amount.
If you're on CE and you need a module that does it all for you, check out magecredit. Their extension comes with API so you can easily take care of updating the store credit / gift card on Magento when someone uses it in a physical store.
