Clover has had an offline feature for payments on all our devices (except our dongle/peripheral solution). It's very heavily used -- thanks to flakey ISPs, routers, WiFi, cellular, etc. We often see people go for a day or two offline.
We let you set limits on count/amount/time of offline transactions. After you come back online we send email a report telling you how many offline transactions you did and how many authorized and didn't authorize. This serves as a feedback loop to encourage fixing connectivity issues.
