credit-card

How does one determine that the card a person is entering is a debit card, check card, or credit card? I am looking at this for web payments in the US only. This is for utility billing. Davy Landman I'm thinking you are getting confused that when you swipe the card in a store the machine knows which kind of card you've got. Although with my Dutch debit card I always got the option to choose.. But I'm guessing the magnetic strip stores more than just the number, and the card readers use that to determine your type of card. You'll just have to join the other applications/sites and ask the user :

What are the PCI rules to follow for storing credit card numbers in a database? 1) is this allowed? 2) if so, what rules do we have to follow? Im looking at this site https://www.pcisecuritystandards.org/security_standards/index.php which document should I be reading here? John Conde 1) Yes, it is allowed but very, very discouraged. Having this information in your database makes you an extremely attractive target for hackers. And if you think you can protect it, think again. Hackers have defeated the security of companies with excellent security. Your security won't be any better. 2) You have

In my country the online payments are not an old thing, the first time i saw a web application taking payments directly to a local bank account was last year. So, Im a newbie coding web payment system. My question is, what are the best practices to store creditcard information into the database... I have many ideas: encrypting the creditcard, database security restriction, etc. What have you done? DON'T DO IT There is simply far too much risk involved, and you will typically need to be externally audited to ensure that you're complying with all the relevant local laws and security practises.

I want to allow my customer users to enter their credit card information so that I can charge them every month. I wonder how one should save this information? Should it be saved in the MySQL database ("user" table) or is this kind of information too sensitive and need to be stored in another place? I have no experience of this and would be glad if someone could advice me how to accomplish this. Thanks. As mentioned above, do not store credit card information in a database. It's a recipe for trouble. Doing so will make you a very attractive target for hackers and, if they are successful in

I tried to check the validation of credit card using Luhn algorithm, which works as the following steps: Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 2 * 2 = 4 2 * 2 = 4 4 * 2 = 8 1 * 2 = 2 6 * 2 = 12 (1 + 2 = 3) 5 * 2 = 10 (1 + 0 = 1) 8 * 2 = 16 (1 + 6 = 7) 4 * 2 = 8 Now add all single-digit numbers from Step 1. 4 + 4 + 8 + 2 + 3 + 1 + 7 + 8 = 37 Add all digits in the odd places from right to left in the card number. 6 + 6 + 0 + 8 + 0 + 7 + 8 + 3 = 38 Sum the results from Step 2 and Step

I'm aware that we can integrate in-app purchases with storekit. but i want to integrate payments using credit card. will apple allow to integrate such libraries? Are there any such libraries available where users can use their credit card for payment of products with in my app? David Brainer Depending on what users are purchasing*, you should be just fine accepting payments in your app. Instead of trying to incorporate some type of payment library into the app I would recommend using a payment API that offloads the work. Take a look at http://stripe.com/ for an example of an excellent payment
