Abstract
After receiving a general display command, an encrypting PIN device recognizes whether the received command corresponds to an expected prompt stored in the device. Afterward, an approved prompt is substituted for the expected prompt, and is displayed by the encrypting PIN device. On the contrary, the received prompt that is not recognized as an expected prompt is displayed without the ability for numeric input while being displayed.
