Debit Cards and End of Day

Southeastern Ohio Credit Union would like to make members aware that daily system updating will affect your debit card.  This happens every evening between 9 and 10 pm and usually only lasts 15 to 20 minutes.  During this time, our system is updating and closing out the current business day.  Unfortunately, while this is happening your debit card will not work.  If you find your card not working during this timeframe, please wait 15 to 20 minutes and try your transaction again.  We apologize for any inconvenience this may cause.

Due to VISA regulations you also may not use a VISA credit card but debit cards are permitted.   You will incur a conveyance fee.
