Iberian Belt Remains of the Revolution Iranian
Iran is at a bad time. The Revolution of the Ayatollahs is saturated and perhaps it is time for profound change in their institutions if they want to be at the forefront and not be considered by the rest of the world as a threat.
The popular revolt motivated by electoral fraud aroused deep sensitivity of the Iranians. They crave freedom and know that in the current situation, it is very difficult to achieve.
What remains of the Iranian revolution that overthrew the authoritarian regime of the Shah of Persia?
Why a dictatorship was changed to another and it seems that if not resolved soon the outbreak of a new revolution could ignite the area.

Whats Discharge Like Pefore Period
Electronic Signature Model
be enlarging on this subject which is one of the pillars in Decree 47-2008, Act for the recognition of communications and electronic signatures.
Is that the same digital signature and electronic signature?
No, same thing. At first I thought yes, but looking for references found in several laws, has defined a digital signature and electronic signature. This digital signature that makes use of cryptography (in whole or part the message), thus ensuring the authenticity, integrity and non repudiation of the message.
To further clarify the definitions here:
electronic signature (copied verbatim from the decree 47-2008, section definitions )
data in electronic form in an electronic communication affixed to or logically associated with, that can be used to identify the signatory in relation to communication electronics and indicate the signatory's approval of the information contained in electronic communication.
For data could refer for example, a sound or mark that they are adhered to or associated with the document in order to indicate authenticity (intention to sign).
advanced electronic signature (copied verbatim from the decree 47-2008, section definitions)
electronic signature that meets the following requirements:
a) Be linked to the signatory only.
b) Allow the identification of the signer.
c) have been created using means that the signatory can maintain under his sole control.
d) be linked to the data referred to so that any subsequent change of the data is detectable.
With this we can conclude that the digital signature is a type of electronic signature ensures the authenticity and integrity of the message.

Since beginning the project
digital invoices 
since last March 31, 2004
The initiative of the Electronic Invoice defined by the SAT was defined optional, however in the course of time is an evolution that should be adopted in different types of taxpayers.
A living example is what has happened with the primary sector that previously had been using the model of AUTO BILLING facility has now been repealed and are forced to use a PACFD authorized by the SAT for Electronic Invoice. This type of process to make the AUTO CHECK PACFD is contemplated that the entity responsible for the administration of the folios, the stamping of digital invoices from both the primary and the service provider.
should generate 2 impressions of such receipt to be signed by the producer and the deduction can be made of this proof of the flat tax.
Another example can be seen was that of models of self printers who had the facility perform the billing on their own to meet the requirements of Art. CFF 28 and 29, which struck down where the alternative was to return to the pre-printed forms (Print Authorized SAT) and / or use electronic billing.
self The universe is about 1,200 printing companies that were in this model where 80% of them migrated to a CFD solution.
market alternatives in terms of electronic invoice solutions focus on 3 models:
Sale system (software)
Service Income (Outsourcing)
Develop your application
Where the companies are using service providers for the short time of implementation. Since most companies believe that their critical sales information can be known by others.
But as has been acceptance of electronic bill now?
Different industries have taken the issue of electronic bill allowing them to make big profits:
- per print cost reduction, messaging, backup, search.
- Process Automation.
- Times.
However There are some fine points that have not been considered by some companies that are doing their issuance and / or reception without meeting the basic rules such as:
If electronic invoice is generated should the be for all customers (only financial statements that dictate what can be done.)
The folio of bills is provided by the SAT in all series and must begin with # 1.
- must report monthly to all CFD force or canceled.
- must use the Digital Certificate Seal not the electronic signature.
- If you hire a service by a third, it must be certified by the SAT.
On the other hand we found many companies receiving CFD do not know how to validate that the above is that made by the issuer properly.
- Another major points that have been detected in models of integration of electronic invoices with business partners is that they are using intermediaries that are affecting that if they want to receive mail directly and bill the force to recruit half of connection with them, coming to repeal every invoice sent or received costs ranging from 0.78 cents to 2 dollars per invoice. what is represented by information transfer costs.

- If you have questions and want to implement a project as successful digital invoices purchase the book electronic billing.
