Whats the difference between an Omron V3A amd V3B?
Both the V3A and V3B family of readers are exactly the same physically. The V3A family is white or cream colored, while the V3B family is black. Sometimes the V3B family comes with a molex wires connected to all the pins of the reader. This can be helpful when building a reader, but not needed. V3B’s tend to me more expensive, I guess because people like black.
