How to Start a Handheld Transaction Using 802.11 Wireless

DynaPro Go models that provide an 802.11 wireless connection can be configured to start transactions in
one of two ways: Always Listening, where an operator would generally initiate a transaction from a
point of sale or similar host, or Device-Initiated, where an operator initiates a transaction from the device
keypad.
In solutions designed for handheld / roving operation using Device-Initiated mode, an operator uses the
device keypad to remotely signal the host to start a transaction by following these steps:
1) Make sure the device is connected to a wireless access point and has good signal strength (see section
7.2 How to Read Device Status).
2) On the screen, press
Welcome
a signal to the host that it wants to initiate a transaction, and shows
3) The host responds to the request by initiating a connection (if TLS is enabled, the connection will be
secured by TLS). If the host doesn't respond, the device shows an error on the display and terminates
the operation. If the error was a temporary issue (such as a network outage or out of range), the
operator may repeat the previous steps to initiate the transaction again.
4) Depending on how the host software is designed, the host sends various messages requesting that the
cardholder or operator enter additional information, and the device requests payment as described in
section 7.6 Card Reading.
5) If the device is not charging, and there is no network activity or user interaction for 2 minutes, the
device closes the wireless connection automatically and powers down to conserve power. If this
occurs in the middle of a transaction, the host should cancel the transaction and the operator should
repeat these steps to initiate the transaction again.
In solutions designed for transactions initiated at the point of sale using Always Listening mode, an
operator uses the point of sale to start a transaction by following these steps:
1) Make sure the device is powered on.
2) Make sure the device is connected to a wireless access point and has good signal strength (see section
7.2 How to Read Device Status).
3) Start the transaction using the point of sale's interface (see the point of sale documentation for
details). Depending on how the host software is designed, the host sends various messages requesting
that the cardholder or operator enter additional information, and the device requests payment as
described in section 7.6 Card Reading.
4) If the device is not charging, and there is no network activity or user interaction for 2 minutes, the
device closes the wireless connection automatically and powers down to conserve power. If this
occurs in the middle of a transaction, the operator should cancel the transaction on the point of sale
and repeat these steps to initiate the transaction again.
