Good security equipment is mandatory for business notebooks. The T440 offers hardware features like a fingerprint reader, an integrated TPM chip as well as a SmartCard reader (not available in our review configuration). Another security feature (similar to the predecessors) is the drainage system of the case and the keyboard, respectively. You can see three small openings at the bottom of the base unit where fluids, which get into the case via keyboard, can drain off without damaging any sensitive components inside the case. The ThinkPad can also handle larger quantities of fluid.
