standby mode.

The contactless reader is on the back of the terminal. It comes with a battery
already installed, and a Micro SIM card, if this was part of your order.

The A77 is a touchscreen device, and you can navigate around menus in a way that
will be familiar to most android users. When charged, it typically displays the
Payments home screen.

➔ set your terminal up in a convenient location

The charging port is on the top of the terminal. It is a standard USB-C port. You can
charge the device by plugging the charger cable (supplied) directly into a power
source, a PC, or an in-vehicle charger.

You can also charge it by placing it on the base station.


You must have a WiFi or a mobile signal to process transactions using the A77. The
terminal is shipped with Mobile & WiFi capabilities. If you have requested a SIM, it
will have the SIM installed.

Clean it with a soft cloth. Do not use water, cleaning agents, or abrasive materials.

credentials. The user ID will be 1234, you will then be prompted for a password.

The first time you enter this, the password is 0000. You will be prompted to change
it before you can process any transactions.


Users of the A77 will process transactions using the POSitive app.

Logging in to the POSitive app

When you first turn on the terminal, the initial screen is displayed, showing the date
and version of the software you are running.

  1. Tap the Payments icon to progress to the next screen.


You may see the following error/ notification:

➔ Error message - Comms Limited
➔ No Wi-Fi or Active SIM Found. Operations will be limited.
➔ Option - Dismiss

This is displayed if there is no SIM card, and you are outside a connected Wi-Fi.

  1. After a brief pause, you will be prompted for a User ID and a password.
  2. Key in the login details provided to you. They will consist of a numerical User
    ID and password.


You will be prompted to change your password once you have logged in for the first
time. If you wish, you can choose to save the credentials.

  1. Having successfully logged in, you will be presented with the home screen,
    with the Main Menu tab uppermost.

Doing a Test Transaction

It is a good idea to do a test transaction with your own card, for a nominal amount
of, say, 1p, to make sure that everything is working as expected.


Users/cashiers must log in to the terminal before they can process transactions.
You can set the amount of time that can elapse before the terminal goes into
standby. You can also set brightness level and other display settings.


The A77 only offers email receipt capabilities as the terminal does not have a till
roll holder installed on it. Sending email receipts is quick and simple once a
transaction has been completed.

Once a transaction has approved / declined the below screen will be displayed.

You can then view these receipts on screen to confirm any information you wish. If
the cardholder requests a copy of their receipt, simply select the “MAIL
CARDHOLDER” option and enter in their email address.

Once this is completed you can press DONE and the merchant copy of the receipt
will be automatically emailed to the Merchant Address email that has been loaded
to your terminal.


Please note that the merchant receipt is ALWAYS sent to the merchant email
address, there is no option to skip this.

As with printed receipts, you can also use the reprint manager under the main
menu, to view on screen and email copies of both Merchant + Customer receipts
if you wish.
