USB stick security key- authorisation tool for accesing account and localized boutique prices.
While providing extra security it could also give ability to pay for game in prices adapted to local currency. Only initial payment would require usage of one of the presently available payment methods. Once purchased security key would allow game server to localize player machine for the purpose of determining local currency and prices in Boutique (based on GPS receiver built into stick). That option would allow non-EUR/USD currency zone players to get offer localized to their location and therefore expanding to other previously unavailable markets.
I understand that target customer now is either EUR/USD zone player or VERY rich person from other countries.
