Stakk (ASX:SKK) expanded its partnership with T-Mobile Money, the digital banking offering by Nasdaq-listed T-Mobile USA, according to a Tuesday filing with the Australian bourse.

Expanded services now include Risk IQ and Auth IQ modules, both within the company's IQ Embedded Finance offering, the filing said.

The expansion is expected to increase transaction-based activity across the platform and "materially" enhance the anticipated revenue trajectory of the partnership, per the filing.
