A former co-worker of mine wears a bunch of IT hats for the Royal

also.

They have mainframes running mostly Unix, and their apps are decidely
*not* legacy apps.


What non-Linux Unix varient runs on Z series, or have we subtlely
switched the topic here? If it is not Z series, or one of the other
"traditional" mainframe systems from the "BUNCH", what architecture s
it? I have heard a lot of systems called "mainframes", where that
terminology is at best, "in dispute".


Yep, but what a large portion of banks do run these days are those
"mainframes" of disputed terminology.


The banking industry has simply changed too much for them to continue
using legacy apps - they have little software that is more than five
years old.

On what systems are they running check processing? I am not aware of
anyone besides IBM and Unisys who make MICR readers, etc.



Is check processing really a significat part of banking any more?
I would guess that check processing is one of the driving factors in
funding for OCR research. Really bad innput, highly important to get
right, large volume. One more place big business is screwing the
customer, now that banks don't have to return your check but can
provide some transaction record instead, you have no piece of paper to
bring to court if that becomes necessary.

Without a way to prove what was on the check you have more problems and
the banks have less cost.

The IBM MidAmerica Employee Federal Credit Union, now the Think Federal

checks with the built in carbon which, together with the account
statement make pretty good proof. And as a last resort you can get hard

Only had to go to the hardcopy once.

And about the wonders of those debit cards....
DECEMBER 14, 2005 (COMPUTERWORLD) - A victim of the recent Sam's Club
security breach suggests that fraudsters may have stolen credit card
information by using illegal "card-skimming" devices attached to the
pumps at the company's gas stations. The fraudulent activity may also
have been going on for a longer period than that suggested by the
wholesale giant, and it may affect thousands of people (see "Update:
Security breach at Sam's Club exposes credit card data").
Sam's Club, a division of Bentonville, Ark.-based Wal-Mart Stores Inc. ,
said in a brief Dec. 2 statement that it was investigating a security
breach that had exposed the credit card data of an unspecified number of
customers who bought fuel at its gas stations between Sept. 21 and Oct.
2. The company said it was alerted to the problem by credit card issuers
whose customers were complaining of fraudulent charges on their statements.

Apart from saying that "electronic systems and databases used inside its
stores" were not involved, Sam's Club officials have refused to disclose
what happened. They have not returned repeated telephone calls for comment.

The breach prompted the Alabama Credit Union (ACU) to block and reissue
debit cards to about 500 of its customers after it learned of the
problem last week. The ACU was alerted to the breach by Credit Union
National Association Inc. , according to Kayce Bell, chief operating
officer at the Tuscaloosa, Ala.-based credit union.

Looks like thousands and thousands of folks. And their pins too. I
hope that the contract with the issuer was nice and solid.

starting in the mid-90s, the financial standards x9a10 working group
was giving requirement for new protocol to preserve the integrity of
the financial infrastructure for all retail payments. this eventually
resulted in the x9.59 standard
http://www.garlic.com/~lynn/index.html#x959
http://www.garlic.com/~lynn/subpubkey.html#x959

part of this was looking at threat models. earlier compromises had
been lost/stolen and/or copied magstripes. the cards are a form
of "something you have" authentication ... from the 3-factor
authentication model
http://www.garlic.com/~lynn/subtopic.html#3factor

the issue was that is as relatively easy to reproduce the information
from a card magstripe and/or use lost/stolen cards. the primary
countermeausre has been noticing fraudulent transactions ... and
turning off that specific card/magstripe at the backend financial
processor (from doing future fraudulent transactions).

pin-debit has been considered more secure because it represents
two-factor authentication ... a combination of "something you have"
and "something you know". a basic principle of two-factor
authentication is that the different factors are subject to different
threats and vulnerabilities. however, both the card magstripe
information and the pin are forms of static data ... and onced
harvested, are subject to fraudulent transactions. in a threat model,
static data infrastructures are sometimes characterized as being
subject to replay attacks (i.e attacker reproducing the static data).

in the time-frame of the early x9.59 work, compromised devices were
starting to appear that skimmed (harvested) static information at the
time of the transactions. this defeated basic principle of pin-debit
two factor authentication since the skimming represented a common
vulnerability to both the magstripe information as well as the pin
information.

so an early objective of x9.59 work was to replace static data
authentication with dynamic data authentication ... in part, as a
countermeasure to the emerging skimming/harvesting
threat/vulnerabilities from comprised devices.

part of this resulted in the x9.59 standard requiring that no part of
a previous transaction can be used by crooks for fraudulent
transactions. one common scenario has been crookks skimming an
authenticated transaction and then using the skimmed account number
information in a non-authenticated transactions. the x9.59 standard
requirement, in turn implies that account numbers used in x9.59
transactions can't be taken and used in any kind of non-x9.59
transactions.

when we were doing the work on ssl for the original payment gateway
and e-commerce
http://www.garlic.com/~lynn/aadsm5.htm#asrn2
http://www.garlic.com/~lynn/aadsm5.htm#asrn3

the objective was to use cryptography to hide the account number so
that it couldn't be skimmed and turned around and used in other
(frauduelnt) transactions.

the x9.59 standard eliminates the need to hide the account number
(using cryptography or any other means), since a crook can no longer
skim/harvest any information from an x9.59 transaction (in whole or
part) and turn around and use any of that information for a fraudulent
transaction.

the requirement given the x9a10 working group for the x9.59 standard
was to preserve the integrity of the financial infrastructure for all
retail payments. the resulting standard eliminated skimming/harvesting
(evesdropping on internet links, compromised atm or point-of-sale
devices, data breaches of transaction logs, etc ) as a fraud
threat/vulnerability. x9.59 didn't do anything about preventing
skimming and/or harvesting happening ... it just eliminated that
skimming/harvesting (of any information connected to x9.59
transactions) might result in a fraudulent transaction.

i can even bring this back a little bit to chips ... having

on the subject.
http://www.garlic.com/~lynn/aadsm5.htm#asrn1

which is somewhat the result of a semi-facetious joke I was making
around the time we were starting the x9.59 work ... that I would take
a $500 milsped (chip) part, cost reduce it by two orders of magnitude
in order to make it more secure (eliminating unnecessary features not
only reduced the cost but also improved the integrity/security)
.... misc. stuff about aads chip strawman
http://www.garlic.com/~lynn/index.html#aads

which was designed, in part, for be used for x9.59 transactions.

You may find it is more a dose of "This is the way I do it" rather than the
US in general. I live in the US and use checks only on occasion, and only
because don't want to carry cash and it is easy to pay someone who knows me.
Those who don't want some verification, and still have to worry about bad
checks, etc. Considering that most people will pay for the check printing,
it may not be any cheaper than a transaction fee for ATM but may be more
convenient. I use my debit card almost everywhere, and so far have not had
any problems. I have had some problems with checks, however (had one bad
one passed in my business, which took a few months to fight and get the
funds back, and some other minor issues)

There appears to be a downside for each type of payment for either the
merchant, the bank, the card issuers or the consumer (fraud, no fees to
charge, etc.) so as with most things you will find that everyone has their
preference and considers it superior to what anyone else is doing
differently.

Dean

Nope, just the opposite. The Europeons were telling us that we're wrong
and they're right. "Right" is simply what works. Here that tends t'wards
the check side, but *might* change (no problem, I use debit cards a lot
too). As long as I can write checks (for cash, even) free and using a
debit card costs me money (credit cards even more), I'll continue to write
checks.
