The TN card, which celebrates its second birthday in February, offers rewards to shoppers at hundreds of locations across the TN postcode.
The App will not only allow card holders to get discounts/rewards through their phone, but also will show locations of all the nearby places where the TN card is accepted.
It comes after founder of the TN Card, Jess Gibson was awarded two grants.
Around £8,000 was awarded to the TN card by Low Carbon Across the South and East (LoCASE), a government backed fund aimed to encourage low carbon solutions and protect the environment.
LoCASE made the award after recognising the positive impact the TN card has on the environment by encouraging local shopping, as well as backing the replacement of physical membership cards with virtual ones via the app.
Jess Gibson, said: “I am delighted that both LoCASE and SEBB have recognised the potential of the TN card to facilitate change and are enabling the TN card to grow and develop, with the introduction of an iOS and Android app.
“The app will make membership easier and more worthwhile, whilst supporting our independents with valuable business functionality.”
Ms Gibson added that she has also been awarded £8,000 from the South East Business Boost (SEBB) that provides financial support for start-ups to help them expand.
The TN card app is set to be launched on February 3, the two-year birthday of the discount card, when Ms Gibson is hoping to arrange anniversary parties in both Tunbridge Wells and Tonbridge.
