According to Dexit, the technology was developed to give tag holders greater certainty that their Dexit account will always have instant access to the funds they require to make purchases.

Customers told us that having an automatic credit card refill option would make it easier and more convenient for them to use their Dexit tags, said Renah Persofsky, president of Dexit.

Tag holders can use the new feature by logging in to their Dexit account and inputting their credit card details. Whenever the account balance dips below $20, the credit card will automatically be charged an amount pre-authorized by the customer and the account will be immediately refilled.

Dexit said it expects the service will increase the speed of transactions as well as the transaction values.
