Foreign Account Tax Compliance Act?? what do financial institutions share?

For foreign bank accounts less the 10k USD, when the bank sends your account info to the IRS, what info do the see? do they see payments from other individuals such as friends and family, and it indicating where/who the payment is from? Is my purchase history are credit card subscriptions indicated?

If I ever got a direct deposit check, will the info shared with the IRS indicate who exactly paid me? Also, if I pay my landlord from the same account, can they look into their info?
