web based biometric payroll system

[nullpointer]

@TS you said that in the doc of your hardware there is no PHP included there. If you'll do it in php you need a glue so that you extract data from that hardware which needs you to create php extensions(written in C) or you can use php-java bridge, etc. Php could not solve everything, if can find alternatives that could make your project easier that would better..

can be done with PHP + VB6 using XML-RPC... no need fancy programming churva... all you need is a bridge and the bridge is very much easy....

PC + Visual Basic => XML-RPC <= Apache Server
or
PC + Visual Basic => MySQL Server that if gi allow ang remote connection

try ninyo combination... dont stick to one langauge kay mag libog mo...

the bridge of this system is XML-RPC... VB and PHP has this capability...

if i where to make this, this is what i should do:
1) Create the VB application that will get the biometric information
2) Create XML-RPC script from PHP
3) DONE

for cross-platform.... my theory would be, i havent tried this one yet:

OS + XUL + Python or Java => XML-RPC <= Apache Server
OS + Python or Java => XML-RPC <= Apache Server

hello.. i'll give you something to start. nka buhat nko og project na nagbuhat mi C nga daemon nya kana nga daemon naay html na interface. ang connection nya is C - Perl - PHP/HTML. you can do it man! Good Luck!

Guys, ga ojt ko karon sa isa ka company diri sa cagayan de oro, then ang gipahimo nila sa amo is payroll system kai ilang payroll system DOS pa. suppose to be sa VB unta mi mag program pero gusto nila web based nga biometric payroll system, centralized man gud ilang payroll system, naa sila branch sa davao, cebu, bukidnon etc. then ang payroll nila naa ra diri sa cagayan de oro, gusto nila nga i submit online ang daily time record sa employees para diri ra sa cagayan de oro mag sweldo. kinsa na naka try ani?

I recommend:

1. If you have already the biometric device, then good. If don't, I recommend using PIC/Serial/Parallel/USB interfacing to implement the biometric system. For both cases, the problem lies on the bytes to pass through the internetwork protocols from transmitter to receiver. So,

2. Having get the data from the biometric system, pass it through XML / PHP / or any data gathering web lang. via online host.

3. The receiving end would receive the data from the transmitting end and update the receiving database for the new entry.

EDIT:

An interface between 1 & 2 is to use (suggestion only) any Assembly/C/Perl/any language to get the data from the biometric device; and also save those data to a file; and let the PHP/XML/whatever get the data from the text file. All of these may be combined into one software package.

Pass the data online as an interface between 2 & 3

this why the XML-RPC is made off, an interface of desktop application and server application... besides XML-RPC are secured notably used by most blogging application.. like live writer

murag lisod jud sya buhaton sa PHP, wala man jud manual but I think naa ko idea, dont know lang if this is possible. ang problem man jud diri is the payroll processing and the field employees on how to track them. employees in the field man gud are given daily activity record forms in which they fill up and will serve as their attendance to be submitted pag makauli sila.

here's what i think:
Develop ang payroll sa VB, then create a web daily activity record form. I mean the one developed in VB share the same database with the one developed in PHP. the data from the web form will go to the database nga ginagamit gihapon sa VB. pwede ba ni?

Sa akong tan-aw, ang nakalisud ani is ang fingerprint scanner will be deployed in the branches. In a web-based application, most of the codes are executed on the server-side, not on the client-side where the fingerprint scanners are located. For security reasons, regardless kun unsa imong gamiton nga language or framework, limitado gyud kaayo ang mahimo sa server-side code sa client machine. Maski man gani pag-upload og text file from client machine without user intervention, moagi pa ka sa lungag sa dagom usa na nimo mahimo. Samot na kun mo-interface naka sa usa ka hardware device nga naka-attach sa client machine using server-side code like php. Challenging gyud na kaayo.

But if you love challenges, go for it. You will learn a lot from it, particularly in the field of security.

Duna pud mga biometric device that can push data to a certain IP address. If you are having this kind of device, dali ra ang pag-integrate. I-configure lang nimo ang mga fingerprint scanner to regularly upload data to a certain address (ex. 'http://mycompany/payrollStorage'). Kanang 'http://mycompany/payrollStorage' sample ra na, ha. Pwede ka mogamit sa inyong kaugalingong address basta accessible lang sa tanang mga fingerprint scanner nga tua sa mga branches.

Then you will code your PHP application to fetch and process data from the centralized payroll storage. Since the payroll storage is centralized and is available thru the public internet, be sure to implement a strong authentication mechanism (ex. SSL, mutual authentication, etc...) aron walay hacker nga magbinuang ug upload2x og mga data sa inyohang server.

Just my two cents, mga bay.

Correct.

Plus adding into the complexity, if for example you are accessing the payroll system from a Linux or Mac computers, I doubt if there are device drivers for your fingerprint reader. One solution is to develop a client program in Java, use imaging api to acquire fingerprints (the fingerprint reader will just be another image source), push the results to the web. You can not have a full web solution for this.

Kani bitaw'ng term nga 'web-based' usa gyud ni sa termino nga wala kaayo masabti sa mga customer. Kasagaran sa ila nagtuo nga basta 'hi-tech' nga gani hisgutan, kinahanglan 'web-based' gyud na, wala nay lain. Nagtuo na sila nga kun ang imong programa 'windows-based', wa pa gani ma-release, obsolete na. Nagtuo sila nga basta 'centralized storage', 'web-based' gyud na.

As a software developer, atoang responsibilidad ang pagpasabot sa atong mga client nga dili tanang IT problems masolusyonan og 'web-based application'. Atoang obligasyon ang pag-offer og mga possible solutions (along with their corresponding pros cons) sa ilaha.
