With semi integration, after the developerβs system hands over the transaction to Cardknox, we hand over the transaction to the POS device for processing. The device submits the transaction directly with the bank and at no point does Cardknox have access to the credit card or any other information that passes between the device and the bank. After the device finishes processing the transaction with the bank, the device notifies Cardknox of the transaction result and we forward that information to the developerβs system. Note: This does not apply to a Pax S300 that is set up to process the transaction through Cardknox.
