** Morningstar expects neutral impact on Tyro Payments TYR.AX from Reserve Bank of Australia's (RBA) proposal to remove credit and debit card surcharges
** Says any earnings impact from merchants unable to surcharge should be manageable as only ~30% of Tyro's merchants currently surcharge
** Adds merchant defections among risks to co from RBA proposal, but expects payments-solutions provider's more contemporary product suite, diversified fee structure position to retain or win merchants from competitors
** Forecasts co's gross profit margins averaging 46% each year over the next five years
** TYR rises 5.8% to A$0.9475
** YTD, stock gains 16%
