My foray into the invention journey started in 2003 when I first had an initial idea to reduce the expensive “DNA” problem in the NHS. “DNA” here stands for “Did Not Attend” or “No show” for appointments in GP surgeries and in hospital. I came up with a solution based on a programmable smart card that can function as an alarm, capable of showing electronically the appointment time and producing a loud alarm sound to remind patients of imminent appointments.
The difficult challenge of this invention is this card needs to be the same size as a credit card, so it could readily be carried by everyone in their wallet or purse. I called it the “Activity Reminder Smart Card”. It led me to work with a high tech French company as well as a frustrating dally with a US start-up.
To make it happen, I need to find investment, and then I heard about Dragons Den! Below are two short clips which were shown in February 2005.
Needless to say, the Dragons didn’t get it and I didn’t get the investment I wanted. Nevertheless, perseverance and bootstrapping meant I was able to start the project. Here are some photos of the development:




The ‘ProActive Reminder’, a related product that Heng and I have developed which was also featured in the ‘Journal of Assistive Technologies’ Volume 3, Issue 2 June 2009.
A UK patent for the ‘Activity reminder smart card’ was granted in 2008. Copy of the patent can be viewed from https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2426081
