[DUG] Eftpos Terminal Interface

[Trevor Jones]

Rohit,

  I've written stuff that talks to Syncro from Provenco and the stuff that
Cadmus do.

  In the past, I've written protocol stuff that talks to the devices (and
the banks) directly

  EFTPOS is not fun.

  At best, you'll get a whole bunch of incomprehensible emails from one of
the providers saying that you've failed type-approval on some weird sort of
power-fail test, you'll spend your time fighting with software that won't
install, doesn't work, or expires its licensing shortly after you try to
investigate it, then they approve you anyway.

  At worst, you'll spend your time fighting with software that won't
install, doesn't work, or expires its licensing shortly after you try to
investigate it and you won't get approved.

  Then you'll get audited by one of the banks to check that you are never
storing information that they don't want you to store (although if you
encrypt it, that is OK as long as you can provide auditable information on
who can decrypt it, when they do so and why).

  I kinda like the Cadmus system although I have never installed it.  The
Provenco system is just flaky (dedicated server runs out of memory
frequently - leaks like a sieve, random transaction failures).

  The WHY is always 'coz that is who the customer signs up with.

Trevor

Has anyone interfaced to eftpos terminals in their app ?  Which make and 
models did you chose to support and why ?
