No. Currently, we are accepting only Visa, Mastercard, and American Express cards. However, we are looking forward to adding Interac payment capabilities and others in the near future.

You can send the receipts via SMS, or print them out using a Bluetooth printer.
A refund means that the customer's funds have been transferred from their account to the merchant's account and the merchant would have to transfer the funds back to the customer. Refunds are issued when the transaction is settled, and the customer paid for the goods/service. Void transactions are different from a refund as the customer's funds don't actually get transferred to the merchant. The transactions can be voided as long as they haven't settled in the merchant's account.
Yes, you can. There are set options along with the custom input where you or your customer(s) can choose how much they are willing to tip.
The admin code will be sent to you via your welcome email.
If you require access to your transaction reports, please contact Felix support.
You can search the transaction records using Recent transaction function. Alternatively, you can use other available filters (date, amount, this device only etc.) The FPS reference is displayed in the receipt information of the transaction record.
You can find it in the Felix.Terminal application on the More screen -> Terminal Configuration.
