The default setting for android devices like A35s and Aries8 is to input an operator password when manually inputting the credit card details. To bypass this, follow the procedure below.

Procedure

1. In the Pax application file, go to EDC -> Credit Features > Credit Manual Entry and set Sale to ENABLED.
2. Save and download.
   
3. Do the reverse if you want to add a password when inputting credit card numbers manually on the card reader.

If you want to disable manual entry completely, select disable. You can also select what type of password to use, that is, operator or manager password.
