### AI overview

This work-in-progress toolkit examines how personal, group, and environmental considerations shape behavior, with a focus on pro-environmental sustainability behaviors. It describes tools that use persuasion or coercion to change behavior and draws examples from sales, health, and education research.

### Source excerpt

As part of my work with Good Energy I have been learning why people behave the way they do, and what tools we have to help them change behavior. My focus is on sustainability behaviors, especially pro-environmental (green) ones. Here are all the tools I know with which we can assist, persuade or coerce people into living more sustainable lives. This is a work in progress.

### AI overview

This technical resource describes random credit card numbers that conform to the Luhn (MOD 10) check for testing e-commerce pre-validation. It clarifies that the numbers are not valid for purchases and should be declined by the card processor or bank.

### Source excerpt

Credit card numbers that conform to the Luhn formula (MOD 10 check). Usefull for testing e-commerce sites (because they should get past any pre-validation you do, and be declined at the card processor or bank stage). In testing situations any expiry date within the next 3 years should work Feedback forces me to clarify this: These are NOT valid credit card numbers. You can't buy anything with these. They are random numbers that happen to conform to the MOD 10 algorithm.

### AI overview

The article presents an online generator and programs in Python, Java, C#, PHP, and JavaScript that produce valid MOD 10 credit card numbers for testing payment systems. It also points to downloadable code and a tool for generating test identities.

### Source excerpt

If you just need a bunch of numbers use the online credit card number generator. Python, Java, C#, PHP and Javascript programs to generate valid credit card numbers (MOD 10). Useful for testing payment systems. This generates VISA, Mastercard, Amex, and a whole bunch of others. Get them from darkcoding-credit-card on github, or Download (zip) all versions. If you want to go one step further and generate a whole test identity, try the Fake Name Generator.
