Methods, systems and computer program products for prepayment towards goods or services at point-of-sale terminals

A method for implementing a prepaid currency transaction comprising:

• receiving from a terminal device, (i) a first payment account identifier corresponding to a first payment account having a prepaid currency value stored therein, (ii) a second payment account identifier corresponding to a second payment account, (iii) a payment amount, and (iv) a payment instruction for incrementing or debiting the prepaid currency value stored in the first payment account;
• implementing the payment instruction, wherein:
• in an event that the payment instruction is for incrementing the prepaid currency value stored in the first payment account, implementing the payment instruction comprises debiting the payment amount from the second payment account and incrementing the payment amount to the prepaid currency value stored in the first payment account;
• and
• in an event that the payment instruction is for debiting the prepaid currency value stored in the first payment account, implementing the payment instruction comprises debiting the payment amount from the prepaid currency value stored in the first payment account, and crediting the payment amount to the second payment account;
• identifying a set of POS terminals for implementing a memory update memory within each POS terminal in the identified set of POS terminals, wherein the memory update comprises recording an incremented or decremented prepaid currency value stored in the first payment account as a result of implementing the payment instruction, wherein identification of the set of POS terminals is based on a set of proximity rules that define POS terminal attributes required in each POS terminal within the identified set of POS terminals, wherein the POS terminal attributes required in each POS terminal within the identified set of POS terminals are dependent on identified attributes of the terminal device from which the payment instruction is received;
• and
• performing a memory update within each POS terminal in the identified set of POS terminals, the memory update comprising recording the incremented or decremented prepaid currency value stored in the first payment account.
