Verifone automate signing for development

Developer face 2 main issue with verifone development.
1. No simulator like ingenico and pax.
2. Signing and download process.

For simulator I haven't found any concrete solution.
But for signing and download I have automated signing process using vbs.
Below is vbs script for your reference.

Vfn_App_Sign.vbs

Set WshShell = WScript.CreateObject("WScript.Shell")

WshShell.Run """C:\Program Files\VERIFONE\FST\FST.exe""", 9

WScript.Sleep 5000

WshShell.SendKeys "user id1"

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "user password1"

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "^{ }"

WshShell.SendKeys "user id2"

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "user password2"

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "{ENTER}"

WScript.Sleep 5000

WshShell.SendKeys "{ENTER}"

WScript.Sleep 5000

WshShell.SendKeys "{ENTER}"

WshShell.SendKeys "{DOWN}"

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "^{ }"

WshShell.SendKeys "{ENTER}"

WScript.Sleep 5000

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "{ENTER}"

WScript.Sleep 5000

WshShell.SendKeys "card password1"

WshShell.SendKeys "{ENTER}"

WshShell.SendKeys "card password2"

WshShell.SendKeys "{ENTER}"

WScript.Sleep 10000

WshShell.SendKeys "{ENTER}"

WScript.Sleep 2000

WshShell.SendKeys "{TAB}"

WshShell.SendKeys "{ENTER}"

WScript.Sleep 2000

WshShell.Run "dnld.bat"

1.    Send GPS points(Lon,Lat) and unique ID of device/terminal on server via GPRS.
2.    Receive GPS points and ID from device/terminal.
3.    save GPS points and ID into flat file or database.
4.    Save below javascript code to locate multiple device/terminal on google map.
5.    add auto refresh function to reload page after fix interval of time.

Automate FarmVille click in Vb.net for FarmVille addicted people

I was very addicted to farmville online game. It have some good strategy things and some most boring and painful thing like farming big farm like 20X20.

Then i have write a small program in VB.net to automate farming using auto click.

You can download this program executable from below link.

https://docs.google.com/folder/d/0B5G4itY9P9sfWlJKdlQyT1pOSjg/edit?usp=sharing

or you can download source from below link and generate your own version for auto farming and many other boring things.

https://docs.google.com/folder/d/0B5G4itY9P9sfN2tqRlJXM3RjR1U/edit?usp=sharing

You can see Video at below link to how to use this program.

You need "Microsoft Visual Basic 2010" (which is free) for compilation and make changes.

Happy Farming :)

EMV implementation

If you are working on EMV implementation on any new device.
Please make sure that you have latest EMV testing kit, latest device EMV kernel, Device OS, and latest VISA and Master guideline, latest Device Chip and Pin EMV and CTLS EMV Sample.
Vendor like Verifone Ingenico also provide training and sample for EMV and CTLS.
VISA Chip and Pin, VISA qsVSDC implementation is very easy and works on device default setting you don't need to do much effort to follow their guidelines.
MasterCard Chip and Pin, Paypass implementation is always pain because of their complex guidelines and device setting.
Amex implementation always looks complex but it is simple if they support you.
You can get EMV kit from ICCSolution, Fime, etc...
Master Visa guidelines from Bank.
You also need one good host simulator for fast development. FinSim is best.
You can get helpful documents from website like scribd for APACS, VISA Master EMV, CTLS.

What is EMV and EMV history?
