ReadNotify Digital Certificate Signature Display & Verification

Viewing the next or previous issued signature helps you establish that that the date and time within your original certificate are correct. Remember - many copies of each certificate (including the ones before and after yours) are distributed to many different people and places around the world. Every one of these people and places is capable of verifying and authenticating the true date and time on their own certificates, which locks your own certificate down to one particular moment in time (because all certificates contain a serial number)   This prevents date and time forgery.
