This delay has been cited as a potential problem for SET adoption by merchants and consumers. However, while micropayments have been discussed for many years already, their ultimate success faces substantial challenges. Clearly, a micropayment scheme must be inexpensive, involve negligible delay, and be extremely easy to use.

The drawbacks are the requirement of lots of trust in the server — i.e., weak security; and, more critically, the fact that this obviously requires one centralized, universally trusted, entity.
