The reason is much less sinister. Using all capital letters makes a name (and address, for that matter) easier to read, and prevents spelling and capatilization errors.

A lot of people have unusual capatalization in their names. Like McCormick could also be written Mccormick. A lot of times, it is hard to figure out how a name should be capatalized, especially if the data entry into the system comes from a handwritten document. So, just using all capital letters makes this problem go away.

Another reason is that a lot of letters look very similar in lower case. the letters r and n spaced closely together look very much like a lower case m. (see? rn m). Lower case o, a, u and e also look a lot more alike in their lower case versions than they do in their capital letter versions (oaue) (OAUE).

That's all. If you ever do a lot of data entry (as I do), especially from handwritten forms, this will begin to make a LOT of sense
