Let say it's funny 

but do you have a real answer?

...do you have a real answer?

Not yet, but I have a real question: 

Are you using the end-user’s own credit card or issuing your own card?

Let say it's funny

You can do that with just one click.

Makes a lot of sense for a fee-based parking structure.

The reader only read CC 5 digit smart card ID number

...5 digit smart card ID number...

only 5 digits?  it’s not a uuid?

Is it the pin or issuer id?

Too risky... Think of all the potential skimming opportunities. No need to give some one your credit card details when they don't need it. Also think about the number of times your access card is dropped or lost. Now you lose your cc which has your name and your credit attached to it.

agree.

Why does the customer 'like' the idea UD1?  i.e. what is the benefit to them of doing it?

Is the customers wallet too thin to hold 2 cards?

I would advise the client that just because it can be done does not mean it should be done, nor is it a wise thing to be done.  For the reasons stated by UD3.

I would never allow my card to be used for card access if I were an end user.  That is insane.

If the finance company/bank reissues the card, will it change the access credential?

Does everyone that needs access in this system use the same bank/carry the same type of card?  Or is this a single user or small number of users?

Majority people in Canada can use their CC or Debit cards to access ATM located inside Banks after regular hours

The same concept

Does it actually verify that the card is tied to a person with a open account?

I would say yes,

You have acc you can open door

Here is a sample of AC soft reading CC card

Sure, but might a library card open it as well, or any track 2 formatted magstripe for that matter?

In that case the system is different than what you propose as the data never leaves the door and doesn’t require tie in to a back-end system, and therefore the card never expires.

Next time you’re at the bank try an expired card, $1 says it opens it...

I am using MIFARE Readers

Ok, but I think the point stands that if you can use any MiFARE card to open the bank door, e.g. expired, stolen, then it’s not exactly the same as your application, because there is no backend communication necessary, and the token is only used as a way to say “I’m at least someone who has access to a MiFARE card”, as opposed to granting access to a specific person.

"Ok, but I think the point stands that if you can use any MiFARE card to open the Bank door"

Where did I say that ANY MIFARE card can open a door?

Of course, it has to be part of the AC database

You didn’t say.  That’s why I said “if”.

I do know this, the bank doors to the ATM at my Wells Fargo open to (apparently) any magstriped card.  Probably cuz it makes the system so simple.

So it’s not inconceivable that a mirfare system could work the same way.  Have you tried an expired card or not?

It will- the reader simply looks for a magstripe, it pays no attention to the card data. The ones I've done have no connection to a database or any outside connection at all- it's only a magstripe reader. Made me wonder why the door isn't just kept unlocked. I suppose they're counting on the fact that most people won't know how it works and will assume there is some database connection to their (presumably) valid card.

Uh...no, not the same concept. The magstripe opens the lobby door to let you into where the ATM is. All this does is deny entry to the homeless person that doesn't have a card with a magstripe. There is no audit trail, no log, no user database, no access levels, just unlocks the lobby door.

Smartphones people. Get rid of the inventory.

If you need access to a bank and an access control door.

Unify those two systems, Bye Bye HID. Let the real cyber security teams handle the future integrations development and design.

With a smartphone there is more ownership of the credential, more ways to authenticate those credentials. Many, many ways.

Why use hard coded stamped, printed plastic magstripe, prox, emv chipped pieces of you know what?

Digital people, digital. We live in a world where we must advance our technology, any device, code, services that ages also decays and makes it vulnerable, cloneable, hackable, less secure. Stay on top of it.

Bank card for access control, come on man! That's like people still installing coax and using encoders for ip video.

Happy Holidays to those that agree, and if you don't then you are a Design-O-saur!

Because

when is the last time the battery on your prox card died?

when is the last time your prox card failed after a firmware upgrade?

when is the last time you cracked the screen of your magstripe card?

I don't think this is a good idea, too much risk. Are you willing to accept the risk of card theft either through skimming or database breach?

I think this is a reasonable concern.  I'm not sure how PCI Compliance weighs into financial cards used as access credentials, but in the US it could be argued as mandatory, ie:

To whom does the PCI DSS apply?

A:The PCI DSS applies to ANY organization, regardless of size or number of transactions, that accepts, transmits or stores any cardholder data.

Security/surveillance systems can cause PCI trouble by even sharing the same network equipment/routers as payment card data, so I imagine storing card numbers in the access system could be a showstopper for a PCI auditor.
