Description of the safety directive (E 131)
The GASTROFIX system is a cloud- and app-based POS-System based on an SQL database and complies with POS guideline 2012 (BMF-010102/0007-IV/2/2011) and POS Type 3.

1. Entries, Business Cases, Documents
1.1 In each completed business transaction (transaction), a receipt is issued that corresponds to the POS guideline (item 4.3.) in its details. A consecutive registration number is assigned for this purpose.
In addition, each transaction is uniquely identified with a UUID (Universally Unique Identifier) and provided with an exact date and time stamp, and numbered consecutively for each operation.
This document number and the chronological, sequential numbering ensure that business transactions are recorded in full.
1.2 Each transaction is immediately transferred from the POS terminals to the GASTROFIX cloud servers, where the data is stored unchangeably on the redundant SQL servers of GASTROFIX.
GASTROFIX guarantees its customers and the tax authorities that all business transactions are stored and archived unchanged for a period of 10 years.
1.3 The information stored in the cloud, i. e. on the web servers operated by GASTROFIX, can be evaluated by the customer at any time in a variety of ways (cash desk crash capability). However, it is not possible to change or manipulate the SQL transaction database, since it can only be accessed read-only via the web interface (GASTROFIX Cloud).
The decentralized storage of transaction data, both physically and technically outside the access of the POS-System, makes manipulation impossible.
1.4 If a document does not close an entry of partial services as a business case (e. g. in the case of order cancellation or cancellation), the previous business transaction is not changed or deleted, but an entry number is also assigned for the write-off of this transaction and a unique digital signature (UUID) is created and a corresponding identification as a non-business case takes place.
This means that every entry posted in the system - even if it does not lead to a business transaction - is permanently saved and stored forgery-proof.
2. Fiscal Journal
2.1 At the same time, the contents of the business transaction or the entries to be entered, together with the UUID, are logged into a fiscal journal that runs unmodifiable and unmodifiable.
This logs all the check contents of the business transactions or postings that have not led to a business transaction.
2.2 After each new business case has been posted, the fiscal journal is signed with a UUID and an exact date and time stamp as well as a control total are also stored here.
2.3 Reversals, changes to payment methods or other corrections do not generate any subsequent deletions of transactions or journal entries that have already been created, but generate additional correction business transactions. (At a table where 4 Cola have been booked, but 2 have been cancelled later, the booking transaction of the 4 Cola is not changed, but a reversal transaction is added, which records -2 Cola and records exactly the operator, time and possibly even the reason for the cancellation.
This means that a forgery-proof recording of the business cases that did not lead to a business case is created in the fiscal journal, so that any manipulations are prevented by the conclusion of a business case before the receipt is issued.
3. Control Unit, Data Export
3.1 This fiscal journal and all other transactions are transferred immediately (every 30 seconds) to the external storage medium (SQL server) of the GASTROFIX cloud when an internet connection is established. If the Internet connection is not available, the data is stored temporarily in the cashier terminals and transferred immediately as soon as the internet connection is available again.
Data import into the cloud is only possible via the predefined interface (internal API) of the POS-system and secured against other write accesses.
This ensures data security and unchangeability of the stored content.
3.2 The fiscal journal can be viewed and exported at any time via special reports in the restaurant manager (cloud) (cash-drop capability). This export can be done as table, PDF or CSV format so that the data can be processed automatically by the tax authorities.
In a typical application, a representative of the tax authority will initiate such an export together with the entrepreneur.
In this way, the entrepreneur can quickly obtain proof of complete compliance with the legal requirements.
