Jonathan Craymer

Jonathan pioneered use of matrix pattern authentication in Europe and the UK, in 2005, having hit on the idea of using shapes or patterns on grids filled with random numbers, while working on a PIN reminder. An ex journalist, he has spent most of his working life in the media, including 14 years in local radio in the UK. He has also contributed to half the national newspapers in the UK, and has written for magazines like Auto Express, Woman and Woman's Own for many years.
