Rechargeable Real Time Clock

Products

Use our new driverless Fortress Rechargeable Real Time Clock (RRTC) dongle to defend against circumvention of time-based licensing. When not connected to a USB port, the RRTC runs on its internal battery. Once connected, it runs on a charge from the host USB port while simultaneously recharging its internal battery.

Testimonial

"KEYLOK was the only provider with a feature like CodeVault and we chose KEYLOK for this reason. The Fortress RS dongle precisely fit our need for a secured key storage device. We don't think there is any other product on the market that offers such flexibility at such an affordable price. Without CodeVault, we would not have been able to provide our solution to our customers. From the very beginning KEYLOK has always been very responsive to our needs and we have never had any issues when contacting KEYLOK."

"KEYLOK offered smaller form factors than other providers and the low-profile design and small size of the Fortress RS, combined with the Smart Card processor design, were large factors in our decision."

"I think your proposal is more than fair and I appreciate our relationship. We are very happy with KEYLOK and the Fortress dongles."
