Type-Approved OBM Systems
The following is useful information about OBM systems – please note there are three categories of type-approved OBM systems to cater for different uses.
To participate in an application or scheme of the NTF that uses a Smart OBM system, you also need a certified Application Service Provider (ASP) who supports the OBM system.

TCA also type-approves Smart OBM systems to Category C. Currently, there are no type-approved OBM systems at Category C, however you can find out more about what to expect from a Smart OBM (Category C).
Check out our OBM fact sheet.
Certificate of Conformance
A Certificate of Conformance for each TCA-approved OBM system will be made available by the OBM supplier (or associated agent, distributor or retailer) at the point of supply to transport operators of each OBM system.
The current cost to the OBM supplier for each certificate of conformance is AUD $20 (excl GST).
