Are they compatible with isonas rc-04 and rc-3?

Thanks for your question.I have checked the RC-04 use 13,56Mhz that same with our Mifare S50 card, but we have RC-04 in hand , can not do the testing , so I suggest you buy a 10pcs for testing or connect with RC-04 supplier.

Do these cards work with zkteco locks? are these writeable?

These cards only work with 13.56MHz RFID locks with protocol ISO14443A.yes,it's readable and writable.

Printable with epson L805?

It Can not wiht EPSON inkjet printer, it can printer with Zebra card printer.

Do these cards work with Unifi door access systems? Do they already have a number assigned to them?

There is no number printed on the cards. We have a PASS system. We had to have the administrator add MIFARE as an exceptable format for the system to read the cards. We then had to add the cards by scanning them at the access point. You will not be able to manually add them as there is no number printed on them. There are some cheap card readers where you could get the number for the card to add it manually.
