Keep up-to-date with your banking transactions by signing up for transaction email alerts. This is a FREE service and is very handy. Every time you have a transaction post to one of your Osuuspankki accounts, you will receive an email to the address you provide the credit union, with the details of the transaction.
If you don't want to know the smaller transactions, you can specify a minimum dollar amount to alert you about. What a great way of keeping up-to-date with what's happening with your money!
