Record carrier and method of labelling an article of value
First Claim
1. A record carrier having a secure data storage device storing a plurality of different identification numbers or parts thereof in a sequence, and a further data storage device storing a further number, the further number being derivable in a predetermined way from the value of only one of said plurality of different identification numbers or parts thereof, the further number indicating which one of said plurality of different identification numbers or parts thereof is characteristic of the record carrier, wherein the plurality of different identification numbers comprise successive integers and the further number comprises the least significant digit of one of said integers.

Abstract
A record carrier has a secure first data storage device storing a plurality of different identification numbers in a sequence and a further data storage device storing a further number. The identification numbers are successive integers, and the further number is the least significant digit of one of the successive integers. The secure data storage device preferably includes permanently structured magnetic tape. The further number is derivable in a predetermined way from only one of the identification numbers, thus identifying uniquely which one of the identification numbers is characteristic of the record carrier.
