Overview
Product summary
Review the store description, core capabilities, and common use cases.
Store your credit cards securely within your computer storage for easy use when shopping online.
➤ How it works
Card Manager lets you create an account locally to store and access your cards. Once you will create an account, you can store up to 9 cards that will be encrypted and stored safely within your computer storage. Card Manager then lets you copy and paste your credentials to online shopping sites and warns you if your card is getting close to its expiration date.
➤ More to come
Card Manager will have constant updates that will improve its usage, speed and look. So stay tuned!

Nice job, whatever you can use Bitwarden (https://chrome.google.com/webstore/detail/bitwarden-free-password-m/nngceckbapebfimnlniiiahkandclblb?hl=en), instead. This tool will save not only your cedit cards but passwords too and it cost $0 instead of $5.99. Autofill is only sweet bonus. Isn't that marvelous?
