Consumer advocates advise you to be particularly careful when contracts are to be concluded with a signature on a tablet. “Actually, I could read the contract here and scroll back. But nobody does that, especially not when the seller is impatient and the next customer is waiting behind me,” said the head of the Federal Association of Consumer Organizations, Klaus Müller. Consumers are always surprised by what they have signed. Müller therefore proposes a right of withdrawal for such contracts – similar to online trading, where a purchase can be withdrawn up to 14 days after completion. Consumers still dealt with paper differently than with digitally presented contracts, said Müller. He respects technical innovations in retail. “But then it would have to go hand in hand with more consumer rights and a possibility of revocation.” Up to now, “signed is signed” has been valid in the store https://www.sueddeutsche.de/wirtschaft/.
