A standard smart box consists of:
1. One or more Literature Holders
2. A donation box.
3. A graphic display frame, which holds a graphic to draw people’s attention.
The base Model 1 is the current model, tested in the field by Team ISV. The original model had a larger donation box but the lock was not sturdy enough and there was a case of pilfering. This current model is both secure and convenient and can hold 15-20 small books or 3 soft-bound Bhagavad-gitas.
The larger Model 2 can hold twice the number of books and is meant for high volume locations.
The components for these 2 models can be combined into other varieties. For example Model 1 can be expanded to have two literature holders with the donation box in the middle.
In places where the donation box is secure but the money is not frequently collected a larger box can be used called the CBS-C (see appendix).
