There are multiple ways someone can receive money. When we work, or offer a service to someone, we receive money for our efforts in a form of cash, cheque or direct deposit.
Normally there are two types of banking accounts for employees, the checking and the saving accounts. In order to be able to open a bank account most of EU countries (i.e. Ireland, Spain, Portugal, Greece) you will require the same documents, although some might additional documents, therefore make sure you check with the bank beforehand. Normally you need to have two/three things:
1) ID (identification number)/passport,
2) proof that verifies your address,
3) and/or social security number/tax number (Greece), NIF number (Portugal/Spain),
4) and/or proof of employment.
