There are three fuses on the device that must be blown during the device personaliza-

tion process. Each fuse locks certain portions of the configuration zone as OTP

memory. Fuses are designed for the module manufacturer, card manufacturer and card

issuer and should be blown in sequence, although all programming of the device and

blowing of the fuses may be performed at one final step.
