#What is a digital chip card with a built-in QR code?
#What are the two types of digital chip card technology that relate to performing contactless data transfer between two devices?
Audio-based data management ("ABDM") allows computers, tablets, smartwatches and smartphones that are near each other to securely store and wirelessly share sensitive data or other data that require authentication, using sound as the carrier of information that underlies the data transmission process.
For those who prefer to use cameras instead of speakers and microphones, an alternative to ABDM is QR-based data management technology, or in short, "QRBDM".
The method of data storage is identical to that of ABDM, but instead of sound, the carrier of information necessary to meet the transmission requirements is the QR code. A QR (Quick Response) code is a two-dimensional barcode that contains a large amount of data and can be quickly and easily encoded, generated or created, as well as decoded, read or scanned.
#Set out for the future with QRDBM
QR-based data management (QRBDM) is a solution for secure storage and wireless sharing of sensitive data or other data that requires authentication, as an alternative to conventional NFC (Near-field communication) technology. A QR data file is a unique 240x368 image consisting of a header, showing the card name and cardholder name, and a QR code, which contains details that bring the card into direct correlation with the data stored on the remote database server.
#QR-based data management technology ("QRDBM") allows computers, tablets, smartwatches and smartphones that are near each other to securely store and wirelessly share sensitive data or other data that require authentication, using QR code as the carrier of information that underlies the data transmission process. You can share photos, audio and video files, documents, send text messages, or make secure payments.
