TI

• SR-52
• 59
  

HP

• 65
• 67
• 97
• 41C
• 71B
• 75
  

Other

• Casio PRO fx-1
  

(Of these, I own the 2 TIs as well as the HPs 67, 97 and 41CV)

Notes

• HP-41C seems to be the only one where the card reader is not built-in
• I have seen the Casio calculator exactly once, when a high-school friend brought to class his dad's
• HP-97 seems to be the only non-handheld of the lot
• I find remarkable that the first (?) programmable handheld calculator, the HP-65, already had a built-in card reader
  

If they don't have to be handheld, the Victor 4900 had one. The 4900 was strange. It had no display, just a printer. Also, it had 14 digits and all the usual trig and log functions but no scientific notation. If your answer was > 10^14 or < 1^-14, it errored out.
