Tricky question.

Whilst you no longer require a fund raising number in order to raise funds under the Non Profit Organisation act it could be prudent to register as a Non-Profit Organisation as it would certainly add to the credibility of the service offered and would provide a structure to ensure all funds are duly paid over for the purpose they were donated. Given the high risk of fraudulent beneficiary claims, it would be prudent to manage the endeavor from within a Company to reduce personal potential liability.

Legislation, regulations and terms you need to consider:

1. The Lotteries Act; the structure and nature of the transactions should in no manner appear to offer any element of chance or the awarding of any monetary or other prizes.
2. Income Tax act; the transactions need to be structured in such a way that the donations do not constitute gross revenue in your hands.
3. National Payments Acts; the terms of payments should not constitute a payment service if the funds are to accumulate for more than 24 hours;
4. The Bank's merchant card agreement in relation to third party payments, one can look to holding the collected funds in a trust account;
5. Liability for misrepresentations; you would need to do reasonable screening of beneficiaries in order to not give credence to fraudulent misrepresentations, whilst at the same time making the benefactors alive to the possibility of potential fraudulent beneficiaries and disclaiming any liability in the terms of use.

In summary, it is plausible but the you would have to be attentive to the vehicle (non-profit company etc), the means (payment methodology) and the risk posed by misrepresentation.

I trust that the legal information and perspective provided is helpful in assessing your position going forward. I am always happy to clarify any aspect of my answer should you so require.
