Prepayment Solution
Prepayment Token Decimal (PPTD)
The Prepayment Token Decimal (PPTD) is a 19-digit decimal integer.
The most significant two digits of the PPTD are between 73 and 96, this being the
result of the addition of 7,394,156,990,786,306,048 (the K-Class 5 Offset) to the
decimal representation of the binary Prepayment Top-up Token (PTUT) to
distinguish it from other standard transfer specification (STS) defined tokens.
Prepayment Top-up Token (PTUT)
In binary form, the PTUT is an unsigned 64-bit integer (8 octets), constructed as
shown in the table below.
Class 5 Token
This format does not overlap with the framework provided by the existing STS
specification and indeed is a new domain of operation outside that of STS token
classes 0, 1, 2, and 3.
PTUT Format - Bit Assignments
PTUT Component Value Bits Note
PTUT Lead 0B00 63–61 Fixed value
PTUT Sub Class 0B000 60–57 Fixed value

PTUT Value Class
0B0 if PTUT Value is to be
interpreted as multiples of 1/100
of currency unit
OR
0B1 if PTUT Value is to be
interpreted as multiples of
currency unit
46–45
If currency unit is set to GB pounds on
the ESME or GSME:
0B0 means PTUT Value will be
interpreted as GB pennies;
0B1 means PTUT Value will be
interpreted as GB pounds.
PTUT Value
The quantum of the PTUT
expressed as an unsigned binary
number of 13 bits in length, so
with leading binary zeros where
required
44–32
Thus, the maximum value is either:
£81.91 if PTUT Value Class = 0B0;
OR
£8,191.00 if PTUT Value Class = 0B1.
