Strategy
Tokenization
Replace stored card numbers with non-sensitive tokens. Removes storage systems from PCI scope entirely.
What it does to scope
Removes card-data storage systems from scope entirely. What is left in scope is the tokenization boundary, not the datastore behind it.
What it is priced against
Usually priced per token or per transaction by the gateway, and often already included in what you pay it. Check before you buy it twice.
Trade-off
Vendor dependency. Tokens are not portable between providers.
Common providers: Stripe, Braintree, Basis Theory, VGS, TokenEx
