More than 16 million combinations are available in a new range of electronic serial numbers introduced by Flint for key fobs, access control systems, burglar alarm and other security applications. Five devices in the Holtek HT6P20 range provide levels of security from a factory-set device to one in which some digits are user-settable, identifying, say, the area from which code was transmitted. A price of less than £1 is quoted for a low power tagging solution based on a Holtek 48000 series 8-bit micro.
