Con's of Mobile wallet: from wallet&applet development up to OTA perso and OTA lifecycle management of the product (TSM, cardlet, and wallet, etc), it is still an expensive tranzactional channel.EMV plastic remains the cheapest and fastest (the biggest tranzactional Con of mobile is "the battery lifetime" and "huge battery draining on some Android smartphones with some bad developed apps", on the second place after cash which from speed point of view still keeps the king's place.I personally estimate that mobile wallets will replace cash and plastic after around 15 years.
