A few years ago when making an online purchase and wanting to pay by paypal, one would have to log in to paypal with their traditional palaver. The last year or so, the tie-ups between p'pal and goods/service retailers automatically log me in to p'pal simply by clicking on the p'pal button on the retailer's site. On finishing the p'pal payment process, p'pal automatically sends me back to the merchant site without actually logging me out of p'pal. I know that because I always check these days by leaving the merchant site - and also quitting/renewing the browser - and going back to p'pal to find that i'm already logged in. So then i simply log out and job done. Electronic cash services seem to get scammier and scummier every year.
