{"product_id":"pos-retrofit-adapter","title":"POS Retrofit Adapter","description":"\u003cp class=\"ak-lead\"\u003eConnect any payment software with any payment hardware: Akrodyn POS adapters translate between USB, MDB, OPI and Wi-Fi in both directions.\u003c\/p\u003e\u003cp\u003eThe payment infrastructure in vending machines, kiosks and checkout terminals is a patchwork of protocols: the cash register speaks USB, the payment terminal only understands OPI (Open Payment Interface), the coin validator uses MDB. Akrodyn POS adapter boards handle the complete protocol translation: timeout handling, channel management and transaction processing are fully integrated.
