For top-mount F3 readers, the mounting hole should be no more than 1.25" from the front edge.
Please indicate the number of readers mounted MORE than 1.25" from the front of the machine, as additional mounting hardware may be required.
F2 to F3 upgrades are very simple, use the same mounting and harnesses, takes about 3 minutes per machine.
F1 to F3 upgrades require the mounting hardware to be changed, can take up to 20 minutes on some machines.
If top mount F3 card readers are required a new mounting hole may be required if not currently within 1.25 inches from front edge of the machine.
