Question

Which British company announced, in 1960, a computer which introduced the use of core memory and was based on decimal instead of binary?

Answer 1

1940s
A patent application for "Classifying Apparatus and Method", including description of both linear and bullseye printing patterns, as well as the mechanical and electronic systems needed to read the code was lodged in the USA in 1949. An early use of one type of barcode in an industrial context was sponsored in the 1960s, and barcodes were introduced into a retail context by a large chain (Sainsbury's) in the UK in 1971..
