An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set. ## Claims ### Claim at position 1 1-74. (canceled) ### Claim 75 A certification authority, comprising a plurality of intelligent display devices, each intelligent display device comprising: a processor; a memory; a verifiable display for displaying a visible-message; a power source; a communication circuit; and certification circuitry; a remote system, the remote system arranged to send and receive messages regarding the visible-messages using the communication circuits of the respective intelligent display devices; and wherein the certification authority generates certification information regarding the visible-messages. ### Claim 76 (depends on 75) The certification authority of claim 75, wherein the certification circuitry includes determination circuitry for determining the visible-messages displayed by the verifiable displays of the intelligent display devices. ### Claim 77 (depends on 76) The certification authority of claim 76, wherein the generated certification information comprises; determined visible-messages, determinants of the visible-messages or dependents of the visible-messages. ### Claim 78 (depends on 77) The certification authority of claim 77, wherein the determinants of the visible-messages are selected from a group consisting of: (1) content of the visible-message, (2) write-messages that determine the content of the visible-messages, (3) rules or pre-loaded content used to generate write-messages, (4) communications signals from, and identification information of, the message authority and other authorized 3rd parties, (5) monitored conditions, sensed data, geo-positioning or location information used to generate write-messages, received (6) identification information regarding the intelligent display device, and (7) timing data. ### Claim 79 (depends on 77) The certification authority of claim 77, wherein the dependents of the visible-messages are selected from a group consisting of: (1) actions, (2) commercial and non-commercial transactions, (3) services and (4) rights. ### Claim 80 (depends on 76) The certification authority of claim 76 wherein the generated certification information comprises determined visible-message-periods, each determined visible-message period being the period of time between the determination of two determined visible-messages. ### Claim 81 (depends on 80) The certification authority of claim 80, wherein the visible-messages-periods are determinant, or the visible-message-periods are indeterminant. ### Claim 82 (depends on 76) The certification authority of claim 76, wherein the generated certification information comprises a historical record of determined visible-messages and determined visible-message-periods and their determinants and dependents. ### Claim 83 (depends on 75) The certification authority of claim 75, wherein the memory stores a historical record comprising generated certification information. ### Claim 84 (depends on 80) The certification authority of claim 80, wherein responsive to a transaction system or user, the certification authority provides certification information for a particular moment in time or during a period of time for one or more intelligent display devices using historical records. ### Claim 85 (depends on 75) The certification authority of claim 75, wherein responsive to a transaction system our user, the certification authority provides certification information regarding the visible-messages of one or more intelligent display devices, the certification information generated by the certification authority in response to the request. ### Claim 86 (depends on 75) The certification authority of claim 75, wherein responsive to receiving information [regarding visible-messages presented by one or more of the intelligent display devices from a transaction system or user, the certification authority verifies or certifies the received information using certification information for the respective intelligent display devices. ### Claim 87 (depends on 75) The certification authority of claim 75, wherein the certification authority is configured to generate digital certificates to accompany certification information. ### Claim 88 (depends on 75) The certification authority of claim 75, wherein the certification authority is configured to encrypt certification information or digital certificates. ### Claim 89 (depends on 75) The certification authority of claim 75, wherein the certification authority authorizes transactions, services or rights dependent on certification information. ### Claim 90 (depends on 89) The certification authority of claim 89, wherein the services are selected from a group consisting of (1) independent determination, verification of visible-messages and visible-message-periods and related events; (2) monitoring, compliance, analysis, analytics, auditing etc.; (3) fraud detection; (4) notification, alarm/alerts; and (5) risk determination/assessment. ### Claim 91 (depends on 89) The certification authority of claim 89, wherein the rights are selected from a group consisting of (1) billing, payment, rebates, credits, settlement, conditional/dynamic pricing etc.); (2) returns, shipments; (3) insurance; (4) title issuance, acquisition, or transfer; (5) access to information/content and systems, particularly in context of a transaction; (6) participation/membership programs, associations, promotions; and (7) performance based benefits including successful management of intelligent display devices, visible-messages, and trusted services. ### Claim 92 (depends on 75) The certification authority of claim 75, wherein the certification authority is configured to generate alerts or alarms responsive to the certification information. ### Claim 93 (depends on 92) The certification authority of claim 92, wherein the alert or alarm is visible, audible, haptic or a wired or wireless communication. ### Claim 94 (depends on 75) The certification authority of claim 75, wherein one or more intelligent display devices of the certification authority affirmatively communicates that the visible-messages presented by the verifiable displays of the respective intelligent display devices are as intended or not as intended. ### Claim 95 (depends on 89) The certification authority of claim 89, wherein the affirmative communication is visible or wireless. ### Claim 96 (depends on 76) The certification authority of claim 76 wherein a visible-message determination is made at a specific time or responsive to a specific event, or internal or external signal. ### Claim 97 (depends on 75) The certification authority of claim 75, wherein the intelligent display devices are selected from the group consisting of smart labels, smart cards, medical patches, wearables, packaging, electronic shelf labels, video billboards, industrial or medical equipment, point-of-sale systems, payment terminals, mobile phones and tablets.
