In december 2010 I asked my mom to send me some money from guatemala to nicaragua, and I went to a store that had your sign at the door, but they asked me to show a nicaraguan id, or a nicaraguan passport or to send the money to a nicaraguan person. I had never had this kind of trouble in any country they told me this was the policy. I had this problem in the stores called "el gallo mas gallo" and "el verdugo". You should check this because they are changing the rules of this service using your sign.
