How can my eBay buyer verify/confirm delivery for an item that was picked up in person?

Hello, I sold a fairly high value electronics item to a local buyer on Jan 15. I met the buyer in person to deliver the item. I've marked the item as delivered and we've both left reciprocal feedback. However, Paypal tells me my funds are still on hold, and will be release "within 7 days of verification". I don't have tracking information because I didn't use a shipping service, so how can my buyer make this verification? He paid with a credit card through eBay so he can't verify it through PayPal.

With payments received for tangible goods Paypal would request valid tracking information confirming the item has been delivered to the buyer. As they can validate the tracking information online, once it is delivered they can release the funds. As you have received the funds for a collected item then no tracking number is applicable and Paypal would be unable to release these funds any sooner than the 21 days.

If you mark the transaction as processed then the buyer may have the option on their account to mark the transaction as delivery/satisfied. If the buyer confirms this by clicking on the "Confirm Receipt" button, the funds may be released to you sooner. This is not always guaranteed. 
If not then sadly its 21 days.
