If you are renting out the premise for short and long term stays, what you really need is a good quality digital lock that has only the bare essentials to deliver digital access convenience on a daily basis. This translates to the following guidelines:
What are our thoughts on bluetooth, wifi or smartphone enabled smart digital locks? Or the add-ons that makes these locks accessible over the internet?
We believe NFC, wifi and bluetooth enabled digital locks are mostly specific to certain use cases and generally do not apply to most home owners. In other words, you are paying more than what you (really need). Those features are there to allow a smaller footprint (but passing on the footprint so to speak to your phone which you must now carry with you). We believe pin number and card access is the most important. To require a phone to unlock to to administer is all too impractical in real landlord/tenant life. These features also sometimes double the battery consumption. Also, on the internet-enabled locks, you are subjecting yourself to any security holes that is always present in such implementations (ie now) that allows hackers to (very) simple unlock from a non-trusted source.
Ultimately, for the majority of us, not paying for what we don't need is a practical approach to choosing the right digital lock that delivers maximum value at the lowest price point.
Our customer engagements are short and sweet, and also characterized by professionalism and accuracy. We have been using Xero Accounting software for a while now and we find it a pleasure to use. What we like about Xero is the simplicity in setup (in the cloud which means no server software is needed), ease in access by our staffs no matter where they are and what they use - be it a desktop, a mobile or a tablet. Our interaction with our Singapore digital door lock customers has been professional and prompt using Xero's quote and invoice sales tool. Xero has also just announced availability of integration with UOB bank for bank reconciliation purpose - which we look eagerly to use. [Update Aug 31, 2016: The integration is in effect!]
We believe our Singapore digital door lock customers will find it easier than ever to engage us for digital door lock deployments!
