[Tagging] Bitcoin: Distinction of purchase through website and cash register/Point of sale

In Sweden we got an electronics chain called Webhallen who accept Bitcoin as payment through their website and allows the customer to pick up the goods they purchase at any of the business's store locations. It does to my knowledge not accept purchase of goods with Bitcoin through their cash registers or Points of sale. I would just tag each and all of those stores with payment:bitcoin=yes Some in the Swedish osm community find it confusing to find out at CoinMap.org that a business accepts Bitcoin but does not accept it at the cash register/Point of sale. One in the Swedish osm community told me that he/she asked a question at a Webhallen store at Sveavägen 39 where the personnel replied that they do not accept Bitcoin at the cash registers/Points of sale of that store. More in the osm community want a way to tag that a store accepts payment in Bitcoin only through their website and not at a cash register/Point of sale, vice versa or any combination thereof. One idea that got proposed was payment:online:bitcoin=yes/no + payment:offline:bitcoin=yes/no where online=purchase through website and where offline=cash register/Point of sale Any ideas?
