What makes a counter a checkout register? An electronic credit card reader.
Here it is, ready to place on your counter with everything you need: pin pad, signature capture screen, pen and support.
Model is based on a real life Verifone mx800 but simplified as much as possible to make it as efficient in your scene.
Model was created with 3dsmax 2009 and rendered with mental ray. Archive contains the MAX file and a3DS file. Materials are basic mentalray materials.
