A

API (Application Programming Interface)

A set of protocols and tools that allow different software applications to communicate with each other. SoftSDC provides a REST API for integration with POS systems.

A process where accumulated fiscal data is submitted to the Tax Authority for verification and confirmation. Required periodically or when storage limits are reached.

ARP File

Audit Request Package file containing fiscal data ready for submission to the Tax Authority.

C

Certificate

A digital certificate stored on the smart card's secure element, used for cryptographically signing fiscal invoices.

Cryptlex

The license management and verification service used by SoftSDC for software licensing and activation.

E

E-SDC (Electronic Sales Data Controller)

The fiscal device created when SoftSDC is installed on a device with a smart card reader and valid certificate.

Encrypted Internal Data

Invoice data encrypted by the secure element, which cannot be decrypted or modified without detection.

F

Fiscalization

The process of converting a regular invoice into a fiscal (legally valid) invoice by signing it with the secure element and reporting it to the Tax Authority.

Fiscal Invoice

A legally recognized invoice that has been cryptographically signed by the secure element and reported to the Tax Authority.

G

GSC (General Status Code)

Standard status codes returned by SoftSDC API indicating the result of operations (e.g., 0100 for success, 2100 for PIN error).

H

HTTP (Hypertext Transfer Protocol)

The protocol used for communication between POS systems and the SoftSDC API.

J

JSON (JavaScript Object Notation)

A lightweight data format used for API requests and responses in SoftSDC.

Journal

The text representation of a fiscal invoice, formatted for printing on receipt printers.

M

POA (Proof of Audit)

Confirmation from the Tax Authority that submitted audit data has been accepted and verified.

POS (Point of Sale)

The system or application where sales transactions are recorded before being sent to SoftSDC for fiscalization.

Protocol Version

The version of the communication protocol between SoftSDC and the secure element or Tax Authority.

Q

QR Code (Quick Response Code)

A machine-readable code generated for each fiscal invoice, allowing customers to verify the invoice's authenticity on the Tax Authority website.

R

Real-Time Clock (RTC)

Hardware clock that maintains accurate time even when the device is powered off. Critical for correct invoice timestamps.

Reconciliation

Process where SoftSDC confirms with the Tax Authority that submitted invoices have been received and processed.

RequestId

Unique identifier included in API requests for tracking and debugging purposes.

S

SDC (Sales Data Controller)

Another term for the fiscal device. See E-SDC.

SE (Secure Element)

A tamper-resistant cryptographic chip on the smart card that performs invoice signing and maintains counters.

Signature

Cryptographic signature applied to invoice data by the secure element, ensuring data integrity and authenticity.

Smart Card

Physical card issued by the Tax Authority containing the secure element with certificates and cryptographic capabilities.

SoftSDC / S-SDC

Software Sales Data Controller - the application that transforms a regular device into a fiscal device (E-SDC).

T

Tax Label

The percentage of tax applied to items in a specific tax category.

TaxCore

The Tax Authority's backend fiscal system that SoftSDC communicates with.

TIN (Taxpayer Identification Number)

Unique identifier assigned to taxpayers by the Tax Authority.

Training Mode

Invoice type that creates test invoices without fiscal impact, used for system testing and training purposes.

Transaction Type

Classification of the transaction as either Sale (normal purchase) or Refund (return).

U

UID (Unique Identifier)

Unique identifier assigned to each E-SDC device for tracking and identification purposes.

Unconfirmed Receipts

Invoices that have been fiscalized and potentially submitted but not yet confirmed by the Tax Authority through reconciliation.

USB OTG Adapter

Cable or adapter that allows mobile devices to connect to USB peripherals like smart card readers.

V

Verification URL
