6.6.1 About Reading Cards

The steps for starting a transaction and reading a contactless payment device are different depending on
the device's configuration and on the design of the host software. Host software developers should see
section 8 Developing Custom Software for implementation references. The solution developer should
provide solution-specific instructions for operators to follow. A transaction generally follows this
essential flow:
1) An advanced operator has already made sure DynaProx is configured properly and is connected to the
host (see section 4.3 Connecting to a Host). When the device is connected to the host via USB and
powered by the USB-C connector or RS232, the host software may always keep a connection open to
the device.
2) The operator makes sure DynaProx is receiving power either from the USB connection or from the
RS232 connection, and is awake and powered on (see section 6.5.2 How to Power On / Wake Up
from Standby Mode / Power Off and section 6.3 About the Status LEDs).
3) The operator uses the host software's user interface (for example, a point of sale) to finalize a
transaction amount, then initiates a transaction. In solutions that are designed to respond to
cardholder input events that occur when the device is idle, such as unprompted tapping of a card or
electronic payment device, the host software may respond to those inputs by notifying the host, and
the host software may trigger other operations without being initiated by an operator (for example, the
host software may immediately start a transaction, or alert the cardholder or operator to take action).
4) The host communicates with the device, and reports to the operator when the device is ready.
5) The operator guides and assists the cardholder in presenting payment.
6) The cardholder interacts with the device to present payment. The following sections provide
additional details about presenting each of the available payment methods.
7) The host monitors the progress of the transaction, and when necessary, should report issues to the
operator, who may need to relay the messages to the cardholder.
8) The device reports the success or failure of the transaction to the cardholder and to the host.
