Resmed cards again

I thought there was a link here that showed a hack with a credit card spacer that would allow for a Resmed ResScan card to be read in a non-proprietary reader. Can't seem to find it now. Appreciate it if someone could send me the link.

The Resmed reader is standard ACR33 Smartcard reader with standard ACR33 drivers. The only special piece is the plastic card guide.

To position the narrow ResScan card in the full width reader, you need a spacer to locate the card under the reader feelers correctly. Most users just slice up an old credit card to make a spacer piece of the appropriate width.

Thanks Bill. That's what I thought. You wouldn't happen to know the required width for the spacer?

If you place the resmed card down, with the gold connectors up, and away from you, the spacer needs to be 12mm on the right and 19mm on the left, as near as I can measure it.

Hope this helps,

Colin

Awesome. Thanks Colin. Does this mean that the card would slide into a standard reader contacts up? I've read that the Resmed reader requires the card to be inserted that way, but wasn't sure if that's the way regular smartmedia readers work.

This all comes about, BTW, becuase when my DME came over with my new Vantage she was supposed to have thrown in the software and reader for free. Oddly enough, I got the software but she said she had to charge me for the reader! I don't get these people. Since I already have a multifunction card reader I said no thanks (never used the smartmedia part, though).

I'm not sure which way it will go in your reader. If it goes in with the contacts down, you will need to swap the guides too. I'm using a Resmed reader, I just measured the size of the guide for you.

The software they gave you is probably just a copy of theirs - it's not copy protected. What version did you get?

I think it's 3.3. Haven't installed it yet.

I use an ACR38 reader that I bought from a company in Southern California (~$25.00) to read my ResMed card. I have built a spacer, from 10mm thick material, where the left side is 18mm and the right is 14mm with a 22mm space between them. I built my first one about a year ago.

Hmm, I'm not seeing how that would fit into a standard smartmedia card slot. A SM card is 37mm wide.

The standard Smart Card is 54mm wide or the same size as a credit/debit card. The ResMed card is 22mm wide but the memory and contacts are the same as a standard card. All resmed did was cut a little off the right and a little off the left.

Most full size "contact" smart cards have the contact pad on the "face" side of the card, so with an ACR38 reader (sorry, not ACR33 as I wrote previously) you insert a full size smart card face-side up.

A multifunction card reader wont do you any good. You need an ACR38 reader, see... http://www.acs.com.hk/acr38.php

Cost is typically around USD $30.... http://www.smartcardsupply.com/Content/ ... /ACR38.htm

Here's the card guide I made up a while back for aligning a ResScan card accurately in an ACR38.

It was mostly made by slicing up an old hotel affinity card. The brown part across the top is from an an old bank credit card and I just added that recently to control an tendency for the ResScan card to very occasionally slip over the top of the guide if I wasn't paying attention to what I was doing when inserting it in the reader.

.. and here's what the guide looks like where it usually lives, inserted in the ACR38....

Cheers,

Bill

D'oh! I was confusing Smart Card with a Smartmedia card .

Would something like this work?

Tony,

While the electronic/software standards for the actual Smartcards are now internationally standarised, the electrical device interface from card readers isn't. AutoScan and ResScan are set up to work with the device drivers supplied for the (common) ACR38 card reader.

You need an ACR38 based reader

Nothing else will work with AutoScan/ResScan.

Cheers,

Bill

Since I dont have the ResMed software, would it be possible to import the data to Excel or something?
