A telephone calling card includes a planar card member with a scratch-off label positioned on a surface of the planar card member. The tool may having a cutting tip for drilling a hole into bone, and may have a shaft and sleeve for accepting the cannulated fastener and for driving it into the drilled hole. A spring biases the blocking object towards the needle axis. The user interface further allows a user to selectively specify whether the given query will be executed as an aggregation query, in which case summary information is returned according to the specified result group.
