We are in process of developing a new digital currency using block-chain technology to be used to purchasing goods and services. We require a skilled programmer to develop POS software to process debit cards on any POS system by means of an easily integrated API. We also need a coding system to encode the debit cards to link with user accounts. Besides the POS software we will also require a server side system to process millions of transactions like Visa and Mastercard now process. Previous experience is a must in any candidate.
