Perhaps
the most important requirement for a ticketing system
is being able to confirm with the bank in real-time
that a customer's banking ID is valid, and then proceeding
to debit the customer's account when tickets are purchased
with a credit card or ATM card. Using an embedded
computer located onsite is a big benefit since the
embedded computer can communicate directly with the
local devices. This is an actual case study from Taiwan.
The customer installed the Moxa UC-8410 RISC-based
industrial embedded computer, which features 3 LAN
ports for network redundancy. One port connects to
banking ID approval system, and the other port links
to an IPC. the UC-8410 is also equipped with 8 serial
ports for managing peripheral devices, such as an
LCM for display, a card reader, and a keyboard for
the customer to input ordering requests. |
