Mint: Development Highlights

At a glance

• 2 systems built from scratch for Mint and its customers
• 4 SIM tasks customers now do themselves: bar, unbar, SIM swap and tag
• Every SIM on an account in one searchable, sortable list
• 3 outside systems connected: Mint's SIM platform, a Microsoft staff directory and a text messaging service
• Weekly automatic sync of staff groups into the text messaging service
• Groups of any size, with every member included
• One sign-in for staff, using their existing Microsoft work account
• About 3,000 lines of code across four years of work

What it means for Mint

• Customers serve themselves. Routine SIM requests no longer wait on Mint's team, and a lost phone can be barred in moments.
• Safe by design. In-progress requests are shown clearly, and safeguards stop duplicate or repeated swaps reaching the network.
• Emergency messages reach everyone. Otsuka's text lists follow its staff directory automatically and include staff without a company phone.
• Less admin. Nobody retypes staff lists or keeps a side spreadsheet of who has which SIM.
