An abridged version of cellphone on wallet technique where you put the cellphone on top of a wallet for convenience because it can be taken with one easy swoop. A negative of this technique is that you put all of your eggs in one basket in case it is stolen. Some prefer to keep their cellphone and wallet far away from each other in case one is stolen, the other remains in tact.
