A valuables-holding device in the form of a booklet which appears, when closed, to be an ordinary compositional notebook or pocket diary has a flange or transparent overlay extending around three sides of the inside front cover. A flexible covering plate, with its edge secured to the spine of the booklet, has its free edge capable of being slid behind the overlay. This will cover the space between the back of the covering plate and the inside surface of the front cover of the booklet. The covering plate can be slid out of the overlay, too, to expose that space. Secured to the inside of the front cover is a credit card organizer. The front cover and the covering plate are both preferably formed with a thin sheet of metal. Thus, the space between those components is electronically sealed or blocked from an RFID reader. The covering plate includes a slot for sliding paper money therethrough and into the space between the back of the credit card organizer and the inside surface of the front cover.
