Spokane's STCU bank branches will be closed Friday, in order to install a new customer-friendly computer system.
ATMs, credit union debit cards and credit cards will function normally throughout the weekend.
Direct deposits and bill payments already scheduled online will be processed normally.
All other banking and online processing will be disrupted from Thursday night through Sunday, April 3. And shared branching at other credit unions may be unavailable during the conversion, a press release said.
The system being replaced went into operation in 1985.
The new system is called a PhoenixEFE. The press release noted that the conversion process, including planning and testing, began more than 1,200 days ago.
