PolyDigi Tech Limited is a newly formed start-up in Edinburgh by 4 experienced entrepreneurs from Hong Kong, Japan and Philippines. 

PoloDigi uses technology that integrates the telecommunication technology and mobile network to compare and match the hashed value of half-code between banks and Telcos to complete the authentication process without privacy issue. Updated PSD2 removes SMS OTP as one of the SCA clause. German banks already removed SMS OTP as one of multi-factor authentication technologies due to lack of strong security.

Achievements to date:

  • SimKeyGo was accepted by RBS Accelerator in Oct 2019.
  • Gold winner of 2018 GBA DIT fintech award in  Hong Kong.
  • Granted CN Patent No: 2013 1 0027672.7; Granted US Patent No: US 10230721 B2; US Provisional Patent Application No: 62/926,580
