A lot of readers are from different manufacturers. If you group the manufacturers by the number of readers they have produced we have:

# of reader per iManufacturer# of iManufacturer%
14653.49 %
21416.28 %
355.81 %
455.81 %
533.49 %
633.49 %
711.16 %
822.33 %
911.16 %
1033.49 %
1111.16 %
1711.16 %
2211.16 %


More than half (53%) of the readers are from a manufacturer that made only one CCID reader. 16% are from manufacturers with 2 readers.

My interpretation is that the reader chip has been designed by one of the major reader manufacturers and the reader chip has been sold to another manufacturer.
