Nope, all you need to generate a refund is the original transaction ID. At
least with the processors I use.

You can get the PCI requirements here:

https://www.pcisecuritystandards.org/security_standards/pci_dss.shtml

You are allowed to store the Card number, name and expiration date.
Appendix B allows you to store that unencrypted.

You are not allowed to store the mag stripe, CVC2 or PIN.
