I'm looking for an electronic lock to secure a small, wooden box (breadbox-sized). The box is ordinary: one side of the lid is hinged against one side of the box.
When I look for 'electronic locks' in a search engine, I don't get anything that would do: either expensive, bulky door locks (too big and don't hold in the right direction for a box) or just magnets (which won't hold once the power is cut). I just want something small, which requires power and a signal to release the catch/bolt.
Where should I look or what search term should I use?
(I know this may not be apropos here, but I don't see a stackexchange site where it's more relevant.)
