The original poster indicates that he lives in the UK, but there are likely strong similarities with the US banking system that I am more familiar with: The result is that you are likely going to be unable to be approved for 10 checking accounts opened in rapid succession, at least in the US. Finally, in the US, there is no need to have checking accounts with a bank in order to open a credit card with them (although sometimes it can help if you have a low credit score).
