I have a colleague who received a rather suspect SMS that, at first glance seemed to advise of money rcvd from someone and a few minutes later someone called to say he had sent the money and error and has a crisis of sorts and would like the money sent back.   I have seen this twice.  Tricksters at work.<br /><br />When using mobile money I have always wondered about the privacy of such transactions since one is required to sign a sheet with details of the transactions - details which are clearly visible to everyone.   I note both ZAP and Mpesa have such sheets.   It would only take a keen eye to quickly pick out a number next to a high value, memorise it -  under the pretext of doing a small transaction and then claim a victim within hours of the person depositing money into their account.<br /><br />I suppose unregistered mobile numbers must now be de-activated ASAP.    <br /><br />Be on the look out.
