General PAX Terminals

Q: What's the difference between an Android and Traditional terminal?

Terminal Capabilities

Q: I have a traditional storefront and a mobile sales business, like a food truck or outdoor shows. Is there a device I can use in both?

A: One option would be an A920.  This device can be used on Wireless or Wi-Fi, and also has a docking station that supports a wired LAN connection.  Talk to your reseller for a device that fits our specific needs.

A: All PAX terminals can process tips, either entered at the time of sale or adjusted after the sale.  Please ask your reseller for details.

Q: Can I use the Android device to calculate sales tax?

A: Sales tax would need to be calculated separately on a Point-of-Sale.  The Point-of-Sale would calculate tax and include it in the total sent to the payment application.  Some applications support having a prompt for tax in the transaction.  It will print the tax amount on the receipt and the total tax collected on the batch report.

Q: Can a PAX Android terminal take Apple Pay?

A: All current PAX devices can accept contactless card and device payments, like Apple Pay, Google Wallet, Samsung Pay, etc.  It must be configured in the terminal and with the payment host.

Q: Can I take Debit, EBT, FSA, or eWIC on my PAX terminal?

A: You can process Debit or EBT on an encrypted terminal.  FSA, HSA, or eWIC payments can only be processed if the terminal is attached to a POS that can send the authorization information for those types of payments. An E Series device with an application that supports FSC, HSE or eWIC would be able to process these payments directly.

Q: Can I take gift cards?

A: Yes, we have applications that support gift cards.  Ask your reseller for details.

Q: Can the device email a receipt to my customer?

A: This would depend on a third-party POS application in or connected to the device. PAX payment applications do not email receipts.

General Questions

Q: What is Surcharge Fee?

A: Surcharge is only applied to credit transactions which are processed by a true credit card while legally, debit cards are not charged with surcharge fee.


  • Note that the chip reader will identify the AID of the card. If it identifies that the card has Debit AID, no surcharge fee will be applied to the credit transaction.
Q: What is partial approval?

A: A Partial Authorization occurs when an authorization is attempted for the full amount of the transaction and there are not enough funds available to cover the full amount, so an authorization for the amount available in the account is returned. This allows the cardholder to use the card presented for the amount available and for the merchant to obtain an additional form of payment for the difference. For Prepaid Gift Cards, the issuers will also return a card balance which will be printed on the receipt.

This feature is controlled by the HOST. Card Brands such as Mastercard, Visa, etc. require this feature to be enabled for ALL cards. This is not a feature we can disable. If there are applications without this feature or that allow you to disable this feature it means they have not yet updated to the latest requirements set by the card brands
