In recent events, I learned that some pagers only have receivers. How are discrete messages sent to these devices? How is it authenticated? How do they know the device got the message?

Back in the ancient times when I got one we had to page the weed guy to get weed. We out our phone number + 420 (truly a mastermind of code no one would ever break) then he would page back with a time (ex 20) to roll through the burger king drive thru where he was the assistant manager. Then just ordered a whopper with extra lettuce (another brilliant code guaranteed not to get broken) then we just paid $10 more than the damn sandwich we didn't want but would soon be fighting over.
