Having owned cattle: it doesn't work that way.
No, you don't have lots of reads on small numbers of cattle, depending on where you are. You're not their parents, and you don't care who they hang out with after class. If you're a large enough rancher to segregate groups of his cows, then you keep them segregated for that reason. (For example, you want to keep a group from breeding that season.) That group does not often change. Your main tagging duties are:
1: Calving. (Actually, probably during castrating time -- you've penned up half of that year's calves anyway. Pen the rest.)
2: Buying cattle: tag them as they come off the truck.
3: Selling cattle: new buyer tags them.
4: If you've got a very large herd, and you're controlling batches of them as above, then track them when you batch them. If you've batched them, you did it for a reason, and you're not going to change it more often than once per season. (If that often.)
5: Sure, you're out in the middle of nowhere with the cows, but we're not tracking them real-time by satellite. I guarantee you that even the smelliest hand goes to the bar on the weekend, and I've never known a bar without a phone. Seriously, they just hand the scanners to the boss that night, and he uses this bit of ancient technology called a modem -- at MOST every two weeks.
(Oh, and expense won't be a problem for small farms: they'll chip in and buy one for three or four farms and spend the next ten years blaming each other for losing it and everybody wanting it at the last minute, just like they do for everything else.)
