Bud had seen this all before. The Peacock Bank was running the same racket 
as all the others: If they accepted you, they'd shoot the credit card right 
into you, then and there, on the spot. These guys implanted it in the iliac 
crest of the pelvis, some opted for the mastoid bone in the 
skull—anywhere a big bone was close to the surface. A bone mount was 
needed because the card had to talk on the radio, which meant it needed an 
antenna long enough to hear radio waves. Then you could go around and buy stuff 
just by asking for it; Peacock Bank and the merchant you were buying from and 
the card in your pelvis handled all the details.
