Ashdod QRcode   Hi Andy thank you for your comment and for the QRcode Yes you are right there are  ordinary codes   We were just experimenting with the graphics and used QR type with a blank center for a logo or for a language flag Will replace it soon  by a kosher code   By the way  would you consider developing a QRpedia code with place for logo It will look better bearing the symbol of town logo of museum etc May be even the Wikipedia logo A project will have a unifiedunique look different from any neighbor  thank you Yoram Shoval
