Paper tape had a high error rate (& tear rate).  It chaffed & built
dirt on reader, & absorbed finger grease & misread whether optical
or capacitive readers. Mylar (plastic) was better, stronger.

Often on long paper tapes we'd read several times & compare to
ensure probably no errors. Checksums weren't so often available.

Our pape tape flew so fast through the reader we held dustbins at
~ 45 degrees to catch it. & then reloaded slower back out of bin
onto winder.

Cheers,
