One can "record" N-ride Ediniy ticket on Troika card as well in order to avoid carrying the easily frayed cardboard card of Ediniy for weeks (e.g. to use Troika's advanced chip). The turnstiles of Moscow Metro have monochrome screens which show such data as "money left" (if Troika is used as a "wallet"), "valid till DD.MM.YYYY" (if a social card is used) or "rides left" (if Ediniy tariff ticket is used).
