US Patent 10055721 Replicating online-transaction behavior in offline transactions

Techniques and arrangements for replicating behavior of a point-of-sale (POS) device operating in an offline mode with behavior of the POS device operating in an online mode. For instance, the techniques may insert an artificial delay into an offline transaction, thus causing an end-to-end processing time of an offline transaction to more closely match an end-to-end processing time of an online transaction.
