What is Credit Card Tokenization & How Does it Work? Credit card tokenization is a process by which your credit card number is replaced with a randomly generated series of numbers, called a "token." This token can be used in place of your credit card number when making purchases online or in-store. When you use a tokenized credit card, your actual credit card number is never shared with the merchant. Tokenization is a type of data security measure that can help to protect your credit card information from being stolen in the event that a merchant's database is breached. Tokenization can also make it more difficult for criminals to use your credit card number if they happen to obtain it through other means. If you're wondering how to use a tokenized credit card, the process is actually quite simple. When you're ready to make a purchase, you'll simply provide the merchant with your credit card's token instead of your actual credit card number. The merchant will then use that token to process your payment. Tokenization is just one of many steps that you can take to help protect your credit card information from being stolen. In addition to using a tokenized credit card, you should also be sure to only shop at reputable online retailers and to keep an eye on your credit card statements for any unauthorized charges.
