PoS devices are usually networked. If you don't validate transactions in realtime you would later validate in batch, but that has more risk than validating at the time of transaction.

yeah, a lot of orgs just don't enable that (or don't have a process to enable it as required, and have difficulty pushing out a notice to do so if the network is down!).
Also can only do offline credit card transactions. Can't with our Interac (Canadian-only) debit network. Unsure about Visa/Mastercard debit transactions.
