In case of transaction failures, various factors could be at play, such as issues with the magnetic card, smart card SAM card, card reader, card swiping, damaged or disconnected components, or an unconnected phone line. Here's how our customer service can help you address these concerns:
- We recommend conducting a test transaction with multiple magnetic cards to eliminate card-related issues.
- Ensure that you're correctly swiping the card for optimal results.
- If possible, try manually processing the transaction as an alternative to using the card reader. If manual processing succeeds, it might suggest an issue with the card reader itself.
- To rule out smart card-related problems, verify the transaction using multiple smart cards and ensure the SAM card is correctly inserted into the card slot.
- Confirm the correct installation of the SIM card and check if the local wireless communication network is functioning as expected.
If the problem persists or if you have any questions, please don't hesitate to reach out to our dedicated customer service center. We are here to assist you further.
