Glyph hacking failure same as normal hack?

Are there any consequences in a total failure when glyph hacking as opposed to just hacking normally? Or is a total failure essentially the same as a normal hack?

Solution 1:

Glyph hacking is intended to be a bonus to your normal hacking. It rewards your speed and (muscle) memory by giving you drops in addition to what you'd normally get from hacking. So no, there's no other consequence if you fail to reproduce the sequence that's been proposed to you.

Solution 2:

While Kappei is correct to say that there is no items penalty for failing a glyph back, there is the obvious time penalty - while a normal hack I'd just one tap on the scanner, a glyph hack is long press... wait... see glyphs... wait... trace glyphs. If you're in an even moderately dense portal field, that means you can't hack every portal without stopping walking. If you're not getting any extra items out of the hack, that's going to dramatically slow down your item collection rate per unit time.
