Digital receipt glossary

Customer-friendly definitions for the current TerraGridTech receipt, POS and Wallet journey.

Activation code
A controlled code used during an approved Merchant POS setup. It is not a POS connection key and should be handled only through the supported activation flow.
Business receipt proof
The merchant-facing record of the receipt facts issued for a completed sale, kept separate from a customer’s personal Wallet notes.
Connection test
A zero-credit check that confirms whether approved POS connection access is accepted before creating receipts.
Digital receipt
An electronic record of a completed sale that can be delivered without relying only on a paper slip.
Electronic receipt
A general term for a receipt delivered or stored electronically; on this site it does not imply a specific email or payment-provider format.
Idempotent retry
Retrying the same intended receipt with the same operation reference so a delay does not automatically become a second receipt.
Merchant POS
TGT Merchant POS, the current app used by approved businesses to create supported digital receipts and customer QR codes.
Paperless receipt
A digital receipt delivered without a parallel paper print. The term does not mean the entire service has no material or energy impact.
Personal Wallet metadata
A customer’s own category, label or notes for organising a saved receipt; it does not rewrite the merchant’s receipt proof.
POS connection key
A secret credential for an approved POS client. It must not be placed in URLs, receipt fields, screenshots or public code.
POS system
The point-of-sale hardware and software a business uses to complete billing and related store operations.
Receipt claim
The supported step in which a customer saves an already-created receipt in TGT User Wallet.
Receipt code
A customer-facing code associated with a supported receipt claim; it is not a merchant connection credential.
Receipt credit
One unit of an active receipt plan used when a supported receipt is created. Connection testing and Wallet claim use no additional credit.
Receipt QR
A customer-facing QR that opens the supported claim journey without exposing the merchant’s POS connection key.
Thermal paper
Paper with a heat-responsive coating used for direct thermal printing. Formulations and local disposal instructions vary.
User Wallet
TGT User Wallet, the Android app in which customers can claim and organise supported digital receipts.
