Understand PSAM Card Exceptions

Overview

This section details the common exceptions encountered when using the SmartCardReaderDevice.open method in Q2/Q3 series devices for PSAM cards.

Common Exception Scenarios

1. No Physical SAM Card Inserted:

   • When attempting to open the PSAM card reader without a physical SAM card inserted, the system will throw an exception.

   • Exception Details: 'Code:-6 com.cloudpos.DeviceException: Operation error! Error code = -1, Error message = Operation not permitted'.

2. Device Restart Required After PSAM Card Insertion:

   • Inserting a PSAM card into the terminal does not support hot plugging. Therefore, the device needs to be restarted after insertion.

   • If the device is not restarted, the PSAM card will not be recognized, leading to an exception.

   • Same exception details as above will apply in this scenario.

Important Notes

• It is essential to ensure that a PSAM card is physically present in the reader before attempting to use the SmartCardReaderDevice.open method.

• Always restart the device after inserting a PSAM card to ensure proper recognition and functionality.
