Mini self inking stamp, sized for loyalty cards. Imprint measures under 1/2" (10 mm) in size. Black ink. Internal ink pad lasts for thousands of imprints and is easily replaceable when dry.

INK IS NOT A GOOD OPTION FOR GLOSSY OR COATED CARDS. Ink needs to be able to absorb into the paper to dry quickly, and is only suited for matte paper cards. If your rewards cards have a coated or glossy finish, a punch is your best bet!
