# BIN Scan

* In option 4 (Settings) you will see the option for binscan.
* This will check the card types for all your cards in profiles.csv and save them to bin\_cache.csv. This saves time in checkout so we already know the card type and which flow to perform.
* If you get rate limited on the scan, load proxies into the master\_proxies.txt. You dont have to set it to True in the config.
