That's right. The one I posted above is a charm for the safety and well-being of the family.
However, there seems to be another similar charm of the same price in Meiji Shrine. The only difference is the four characters written on the paper (or what's written on the wood, depending on the type of the charm). If the kanji are 商売繁盛, it's for business success.
