Mpesa Terminology

Since a lot of developers are working on M-Pesa outside Kenya, we thought it would be good to describe some terminology for those interested!

M-Pesa: The mobile money platform
Paybill: A unique 6-digit code used for bill payment eg electricity. Usually has a transaction fee.
Till Number: A unique 6-digit code used for purchasing goods or services. Usually has no transaction fee.
STK: SIM Tool Kit. (That menu that comes with a SIM card)
Daraja: Means Bridge, Usually used to refer to the developer site
LNM: Means Lipa na M-Pesa meaning Pay with Mpesa. These transactions are always triggered programatically.
B2B: denotes transactions between two business/shortcodes.
C2B: denotes transactions started by user.
C2BSimulate: Since C2B transactions are always started by the user. This denotes the mocking of user triggering the transaction.
