Hello,
Has someone experiences with SmartCard readers and Fivewin.
Thanks in advance

Hi
I create diferents solutions with miscellaneous companys.
From DLL, ActiveX, Webservices, rs232, etc..

You can say something more concrete ?

Are you referring to credit cards ? If so:

We have credit card processors with whom we integrate our software. It is actually quite simple. They have the smart card keypad / signature terminal connect to the computer, and it is completely driving by their software ( a DLL ).

Our program calls their dll functions and passes it some information about the order ( Invoice ID #, amount, Client's account number in our system ). Their software then activates the terminal and processes the credit card. When complete, it returns some info to us, including the signature capture, and we use that to print on the final invoice / receipt.

We do not obtain, or retain, any of the credit card information in our system so our clients never have a problem with PCI compliance. It works very well.

Hello Tim,
thank you for your reply.
In Austria tax law was changed and now we must sign bills through a SmartCard reader.
We should send data like bill number, amount, tax, etc. to the Card Reader and get back a signed string.
It should work through APDU.
Thanks in advance and best regards,
Otto

Hello Otto-

Have been absent for a while so I hope this is still relevant.

If it is a matter of picking up the customer's signature while showing some information on the signature pad screen, then you could use Topaz. I use their signature pads to pickup patient signatures for many forms. Topaz comes with a .dll that you can use as an ActiveX control. You can display images, text, buttons, etc. and a signing box or dotted line for the customer to sign. The signature returns on many different formats including a compressed .jpg that you can save to your .dbf or show on a dialog.

I wrote a class to manage Topaz signing pads. Please let me know if anyone needs the code.

Best regards,


Reinaldo.

Hola Reinaldo.

Tengo un Topaz T-S460 podrías enviarme(jd_microexpress@hotmail.com)

Muy agradecido de antemano.

Hi,
What about identity card .

How to read the contend of EID Card ?

Thanks

[reinaldocrespo]

Hello Jack;

EID identity card and a signature pad are totally different animals. The question itself is puzzling to me. I think signature pads are universal. Every country I've been to implements some sort of signature pad as part of commerce. For example, when you pay with a visa card at a restaurant and the they make you sign on an electronic screen that displays messages, a signing line, and perhaps an accept button. That type of device is what I mean by "signature pad".

I have had great success using Topaz line of signature pads. The code I share here allows you to display a message on the pad's screen, draws a couple of buttons to cancel and to accept and a line where the customer signs. Once the customer clicks on the accept button the signature is returned to my FW app as a jpg that then gets saved to a blob field. The code is very old and it is my actual code in production. It is not a sample app but rather the class itself in production for many years. I hope it helps. If anyone enhances the class, please publish it or send it to me so that I may also benefit from your work.

The issue here in the US is the security of the data. My clients do not want to retain any of the card data on their equipment. So, our processing companies have all the information handled between their card reader and their own servers.

Here is how it works.
1) We have the customer name, total, and invoice info which we pass to the terminal API installed on the workstation.
2) The API then pops up a screen and shows the amount to be charged to the card. If no card is present, you can enter the card data. Otherwise, the customer puts their card in the reader, or swipes it.
3) The terminal asks them to confirm the amount, then prompts for a signature.
4) The signature displays on the API popup screen.
5) When OK is pressed on the API popup, a set of data is passed back to our program which includes the transaction number ( which is all we need to process credits or refunds ), and the graphic of the signature. We save both to the invoice file.
6) We then print the final invoice which includes the required transaction information, and the signature.

We use the same process with two different credit card processing companies. It's quite simple, very secure, and our clients never have to worry about all of the legal requirements for protecting the credit card data itself.
