The Multi Function Seca Model 664C Wheelchair Scale has all the specifications of the Model 664 with the added Smartcard feature.  The Smartcard is similar to a credit card that stores the weight of the wheelchair.  Once the Smartcard is inserted into the indicator head of the scale the weight of the wheelchair is automatically subtracted providing you with the weight of the patient only.  Each card can ride along on the wheelchair by directly attaching the special card holder to the wheelchairs as shown below.

The 664 Series is the industry's largest weighing platform allowing even patients in bariatric wheelchairs.  Thanks to the extremely flat platform, the scale is easy for wheelchair patients and the side barriers ensures maximum safety.  The integrated pre-TARE function determines the patient's net weight in seconds and a real advantage is its HOLD function, which continues to display weight in large, easy-to-read numbers even after the scale is no longer in use.

The Seca 664 Wheelchair Scale is portable and folds up and with the built-in casters you can roll the scale away.  The true beauty of the Seca 664 & 664C Electronic Wheelchair Scale over the competition is the collapsibility and easy transportation design.
