Hippolytus or Hipolit (died c. 1027) was an early medieval archbishop of Gniezno.

Theobald of Bec (c. 1090 – 18 April 1161) was archbishop of Canterbury from 1139 to 1161.
 He was a Norman; his exact birth date is unknown.
 Some time in the late 11th or early 12th century Theobald became a monk at the Abbey of Bec, rising to the position of abbot in 1137.
 King Stephen of England chose him to be Archbishop of Canterbury in 1138.
 Canterbury's claim to primacy over the Welsh ecclesiastics was resolved during Theobald's term of office when Pope Eugene III decided in 1148 in Canterbury's favour.
 Theobald faced challenges to his authority from a subordinate bishop, Henry of Blois, Bishop of Winchester and King Stephen's younger brother, and his relationship with King Stephen was turbulent.
 On one occasion Stephen forbade him from attending a papal council, but Theobald defied the king, which resulted in the confiscation of his property and temporary exile.
 Theobald's relations with his cathedral clergy and the monastic houses in his archdiocese were also difficult.

 On the reverse, it may include additional information such as the date when the ID card was granted, expiration date of the ID card, and other such as their fingerprints, and all the owner's information in matrix code.
