Can I use multiple credit/debit cards to collect payment using the Moneris gateway?

Yes, your customer can pay for a sale transaction using multiple credit or debit cards. For each credit or debit card used, a payment authorisation request will be sent to the Moneris Device mapped to your POS register. This is because for Moneris each credit or debit card interaction is treated as a separate transaction. Customer will have to individually authorise these. 
There will be no change in your subscription amount in the current billing cycle if you are only deactivating the Moneris Payment Processor plugin AND not updating your Store / POS count.
Activating or Deactivating this Moneris Payment Processor plugin will not affect your subscription amount for your next billing cycle because the plugin is free.
