When I said "an SD card and a card reader," I meant a flash memory card and a device which reads flash memory cards. I wasn't trying to buy a device which reads credit cards. Sorry for the confusion. I later bought the things I needed from Amazon, and Amazon's computer pointed out that the credit card they had on file for me had expired. I had to enter the new expiration date in order to complete the purchase. I think the problem with PayPal must have been the same, since I keep the same credit card on file there. The only difference is that when PayPal's computer saw that my credit card had expired it told me it needed to see a photo ID. I didn't understand that what it really wanted was for me to update my credit card. I still don't understand why it didn't just say that. Apart from the absurdity of giving a photo ID to a computer that can't see me, and the questionable policy of using an expired credit card rather than asking for the new one, it's much easier to enter a new expiration date and CSC number than it is to scan and upload the three documents that PayPal asked for. Even if I had tried to use the expired credit card in a store, where a photo ID would be of some value, I think the cashier would have asked me for a newer credit card rather than a photo ID.
