154885 one time login pin

i want a one time login script, were by cleint will use his pin only once on my site the next time he try using the pin the system will use invalid pin or used

here is the description.

there should be database with two table. with the name: password, used password.

i will load the password column with my desired password like, 64iutjrjr, 83jh4jh8ej,ufjjfjdjd. etc

while the when ever a client used the pin it should be inserted into the used column so that when someone try using it the next time the system will echo used pin or invalid.

the whole aim is to protect my registration page something like [url removed, login to view]

that mean the above condition must be fulled before the system will redirect the user to the registion page. i want a situation were by the page connot be called from browser except through fulling the above condition.

how much will it cost
