As a merchant, will I be sharing my itemised sales data with Xiippy or anyone else to include smart receipts and rewards within payments?

Answer:                

Short answer: Absolutely NOT.

That's the whole different Xiippy uniquely brings to the table, backed with multiple patents. Other alternatives require you to FULLY trust the data intermediary and possibly banks as well. With alternate providers, it will be like saying "Give us all your passwords and we're good people; we won't be doing anything bad with it". With Xiippy, you are assured you are not in need of trusting anyone with your data as you are not sharing anything in the first place!

• Xiippy uses end-to-end encryption to establish a completely-private communication pathway between you and your customers.
  This means no data gets out of your POS system without being encrypted with keys unknown to the rest of the universe.
• Such data then gets decrypted at the consumers' devices after being routed using cryptographically-generated routing details from consumer card tokens (not card numbers).
• You can generate your own keys as part of the process and only share public keys with Xiippy for increased confidence and assurance of Xiippy's zero knowledge.
• Xiippy is the only company preserving consumer data rights in full by only making data available to them whilst digitising the data that otherwise must remain on papers or be disclosed to other parties as part of digitisation.
• Your itemized sales data will never be visible to Xiippy nor any other party in the universe, including your competitors.
• For high-privacy-needs merchants like pharmacies, this is a MUST have! Imagine disclosing people's medications list to a 3rd party via digital receipts! That could potentially lead to legal actions should the data get ever disclosed to other parties, wantedly or unwantedly (e.g. in a data breach incident)
