One partial answer might be due to utility billing. Back in the 70's our phone bills always came with a punch card with "Do not fold or staple" written on them. You had to include the punch card with your cheque when paying the bill. The card was envelope size, so it was easy to mail out and easy for the bill payer to carry around. But a paper tape would be pretty awkward to handle in this fashion. |
