This may be of some help.
Just returned from Crete after a great two week holiday.
Part of my mission was to open an I-Bank account.
My situation was of having a current account in Greece subject to the usual capital controls that are currently in place.
This permitted a weekly withdrawal of 420 euro (840 if joint) This was unsatisfactory, as, unless I visited i could not access my funds, hence I-Bank.
After several failed attempts at opening I-Bank acct this time Eureka! Apart from requiring a barrowful of documents and being fortunate that a very cooperative and competent gentleman was on duty the process was , although time consuming, pretty painless.
Some of the documents required: (Joint acct) Two passports, two tax numbers(AFM) tax clearance document Two statements of Pension entitlements, verification of residency, telephone no., utility bills, Questions (I kid you not) how many children, how many went to university etc.
After many official stamps and a queue out the door success. we were handed this little thingamajig and told to treat it as if it were the key to the nuclear button.
Eventually, returned home and approached the computer with not a little trepidation. After a few attempts and a wait of a couple of days, mission completed! money transferred.
