A lid that fits the most popular cardboard coffee cups includes a slot for bills and another slot for coins. The slots have scanner tech that counts the money inserted and sends money-insertion signals to a Bluetooth transceiver embedded into the underside of the lid to allow connectivity to a phone app such as one for financial planning, online shopping, or even online banking . A speaker embedded in the lid can be per-programmed with selectable/recordable responses such as "thank you" and "have a nice day".

Also, it could eject counterfeit coins, and torn or folded notes.

//and torn or folded notes.

Give them to me...

Presumably the cyber lid has a processor for payment by bitcoins?

Taking this a little further, why not simply implement the beggars in software? In this day and age, there's surely no need to have them as hardware, occupying valuable space?
