Some users of Samsung Pay, a mobile payment platform used on Galaxy devices, were inconvenienced Monday morning when service was disrupted for about three-and-a-half hours.

Samsung Electronics, which runs the service, apologized in a notice on Monday, saying that while there were errors in processing card payments and registration attempts, the problems have been resolved. 

A Samsung official said the errors were intermittent and did not affect all payments on the platform.

Reports of difficulties with Samsung Pay started to appear on online communities from around 6:30 a.m.

Normal service was restored around 10 a.m.
