Offline authorizations work for contactless transactions that are below the offline floor limit, which is card dependant (currently £15 for Visa, £20 for MasterCard and Maestro). Contact transactions in the UK can be authorized offline depending on your acquirer/processor.
To enable Offline Support:
Offline transactions are processed as Deferred Authorizations (also known as Store and Forward). This occurs when an online authorization could not be performed due to connectivity issues, at which point ChipDNA will prompt the merchant to accept a deferred authorization at the merchant's own risk. Deferred Authorizations will then need to be confirmed within 24 hours. Any Deferred Authorizations that do not reach our platform within this 24 hour period will be discarded.
To enable Deferred Authorizations:
- Send TMS Request to email@example.com with the following information
- Offline Volume Limit (0 - unlimited)
- Offline Amount Limit (0 - $5000)
