Encrypted card devices and recurring payments

We are a RAMP client and are looking at our PCI scope. We thought that installing encrypted card readers and keypads would reduce our scope. I have just been in contact with support and found out that encrypted devices never store the credit card number in the Tessitura databese. It goes directly to Vantiv. This is great for PCI, but means that there is no credit card in Tessitura to use for monthly membership billing. A credit card has to be in the Tessitura database before it can be tokenized, so tokenization does not solve this problem either. Our IT guy wants to know what other organizations are doing about this. Any help? Thanks.
