# FuelApp Release Notes

> What changed in each FuelApp version, and what it means for your integration.

FuelApp is the payment application that runs on the VPOS terminal at the
dispenser. Its version number is separate from the Marshall Pro protocol
version, so a FuelApp release does not change the protocol your POS or
forecourt controller (FCC) speaks. Subscribe to the RSS feed using the icon
at the top of the page to get notified when a new version is added.

<Update

title: "FuelApp 1.10.02: QR e-receipts, site branding, and ANDI support",
description: "Added: QR code e-receipts, a custom card-detect screen with tap-to-continue, a Remove Card prompt after chip transactions, and support for the ANDI terminal integration protocol. Changed: clearer status icons and a site-filtered language menu. Fixed: stop request handling, a startup hang after a terminal update, and eight screen, keypad, and stability defects."

      ### Support for the ANDI integration protocol

      FuelApp now supports ANDI, an additional payment-terminal integration
      protocol, on certain dispenser hardware setups.

      ### Custom card-detect screen and tap-to-continue button

      Sites can now show a branded card-detect screen with a tap-to-continue
      button. This is a per-site configuration, so the same integration can show a
      different card-detect screen at different sites.

      ### Remove Card prompt after chip transactions

      The terminal now shows a **Remove Card** prompt after a chip transaction
      instead of only sounding a beep.

      ### Digital e-receipt by QR code

      After a payment, the terminal can show a QR code the customer scans to get a
      digital receipt. Merchants enable this per site, so the screen does not
      appear unless the site has it turned on.
    </Accordion>

    <Accordion title="Changed" icon="pen-to-square">
      ### Language menu limited to enabled languages

      The language menu now lists only the languages enabled for the site, instead
      of the full list.

      ### Clearer status icons

      The terminal shows clearer on-screen icons for the card-blocked and
      transaction-canceled messages.
    </Accordion>

    <Accordion title="Fixed" icon="wrench">
      ### Card reader ignoring a stop request

      The card reader sometimes did not respond to a stop or cancel request.

      ### App stuck on Initializing after a terminal update

      FuelApp could stay on the **Initializing** screen after a payment terminal
      software update.

      ### Dark screen before the idle screen

      A dark screen could appear for several seconds before the idle screen after
      a card was tapped or inserted. This fix also improves overall app stability,
      including a rare crash and restart after extended use on some older
      hardware.

      ### Frozen screen on a card retry

      The screen could freeze when a card had to be presented again during
      payment. This included a case where **Transaction Canceled** appeared after
      the customer had already canceled on purpose.

      ### PIN pad registering the wrong key

      PIN pad buttons sometimes registered a different key than the one pressed.

      ### Masked entry showing typed digits

      Masked numeric entry did not hide typed digits on some input screens.

      ### PIN keypad layout in Hebrew

      The PIN entry keypad displayed incorrectly on terminals set to Hebrew.

      ### Wrong screen after canceling a payment

      Canceling a payment could briefly show the wrong screen before the terminal
      settled on the correct one.

      ### Old message reappearing

      A previous message could flash back onto the screen for a split second.

      ### Yellow flash between screens

      A brief yellow flash appeared during screen transitions.
