The UZK requires that a written contract be signed “by the party against whom performance is sought” in order to authenticate the document and verify that it comes from its precise source. Some flexibility is allowed regarding the form of authentication, for example. B any symbol or signature can be used if the intention is to authenticate. EDI transactions can be “signed” electronically by containing algorithms in their feeds that authenticate the identity of the sender and act as a “password” – the electronic equivalent of a personal signature. This password can be read by the recipient using an electronic “key”. If EDI trading partners agree on the authentication method to be used in their EDI transactions and want to serve as binding agreements, it seems logical that the law would consider these transactions to be legally binding, in accordance with the intention of the parties. However, since the PEA does not define the importance of “authenticating”, it is impossible to determine the precise legal requirements applicable to EDI signatures. EDI documents usually contain the same information that is usually found in a paper document used for the same organizational function. For example, an EDI 940 order from an out-of-warehouse shipment is used by a manufacturer to order a warehouse to ship the product to a retailer. It usually has a shipping address, a billing address and a list of product numbers (normally a UPC) and quantities. Another example is messages between sellers and buyers, for example. B Request for Offer (RFQ), rfq response offer, order, order confirmation, shipping notification, receipt advice, invoice and payment advice.
EDI is not limited to commercial data, but covers all areas such as medicine (e.g. B patient records and laboratory results), transport (e.g.B. container and modal information), engineering and design, etc. In some cases, EDI is used to create a new flow of business information (which was not previously a paper flow). This is the case of the Advanced Shipment Notification (ASN), which aims to inform the recipient of a shipment, the goods to be received and the packaging of the goods. This is complemented by the use of shipping labels containing a GS1-128 barcode referring to the shipment tracking number.  In many ways, a NPV acts as a service provider and simplifies much of the organization for organizations wishing to initiate EDI. Due to the fact that many companies that start with EDI first often do so to meet a customer or partner request and therefore do not have in-house EDI know-how, a NPV can be a valuable asset.
With the development of EDI and Web technology, new EDI software technologies have emerged to facilitate direct access (also known as point-to-point EDI) between business partners. Modern EDI software can facilitate exchange with any number of file transfer protocols and EDI document standards, reducing costs and barriers to entry….
