Electronically readable system and device with changing codes
An electronically readable device and system is incorporated within and/or attached to an object to validate and/or authenticate the object. Upon activation of the device one or more codes encoded within the device are revealed and are able to be scanned by an electronic device. The electronically readable code changes, such that for each period of time the code is different than a previous period and only the database knows in advance what the code should be for a given period. The scanned code is uploaded to the database where it is compared to a stored code to verify that the object is authentic.
1. An electronically readable device comprising:
a. an anode layer;
b. a cathode layer;
c. an electrolyte configured to contact the anode layer and the cathode layer; and
d. a base comprising one or more electronically readable codes,
wherein after activation of the device, the anode layer depletes to uncover the one or more electronically readable codes such that for a subsequent period of time the electronically readable code is different than an electronically readable code of a previous period of time.
2. A system for validating an object comprising:
a. a database comprising one or more stored codes; and
b. an electronically readable device comprising one or more electronically readable codes which are revealed after activation of the device,
wherein the one or more electronically readable codes are read and compared to the one or more stored codes to validate the object, wherein the one or more electronically readable codes are revealed such that for a subsequent period of time the electronically readable code is different than an electronically readable code of a previous period of time.
3. The system of claim 2 wherein once revealed, the one or more electronically readable codes are able to be read by a human or machine.
4. The system of claim 2 wherein once revealed, the one or more electronically readable codes are able to be scanned by an electronic device.
5. A method of validating an object, the method comprising:
a. coupling an electronically readable device comprising one or more electronically readable codes which are revealed after activation of the device with the object;
b. scanning an electronic code at a first time period;
c. uploading the electronic code to a database;
d. comparing the first time period scanned code to a first time period stored code to validate the object; and
e. scanning an electronic code at a second time period and comparing the second time period scanned code to a second time period stored code to validate the object.
6. The method of claim 5 wherein once revealed, the one or more electronically readable codes are able to be read by a human or machine.
7. The method of claim 5 wherein once revealed, the one or more electronically readable codes are able to be scanned by an electronic device.
8. An electronically readable device comprising:
a. one or more shields; and
b. a base comprising one or more electronically readable codes, wherein the electronically readable codes are prevented from being read by the one or more shields,
wherein after activation of the device, the one or more electronically readable codes become readable through the one or more shields such that for a subsequent period of time the electronically readable code is different than an electronically readable code of a previous period of time.
